public class ComboBoxItem
extends TextItem
implements PickList, HasDataArrivedHandlers
```
The Combobox is a text input field which can show a list of options via a drop-down PickList.
The set of options will be filtered based on the current value in the text field, so only options that match what has been typed so far will be displayed. The set of options can be derived from a ValueMap or dynamically retrieved from a dataSource. See the PickList interface for further settings.
The two most common use cases for ComboBoxItems are:
- With addUnknownValues set to true, the ComboBoxItem acts as a freeform text entry field with the picklist providing essentially a set of suggested completions similar to a URL bar in a web browser.
- With addUnknownValues set to false, the ComboBoxItem acts similarly to a SelectItem where a fixed set of options is available to the user and the text entry field is essentially used to filter which of these options are visible
Other commonly used settings to configure ComboBoxItem behavior are:
- defaultToFirstOption - this will select the first option from the pickList as a default value for the item - and
- completeOnTab which causes the current selection in the pickList (if there is one) to be chosen when the user tabs out of the field, allowing a user to type a few characters and hit tab to auto-complete to the first matched option. completeOnTab is automatically set to true if addUnknownValues is false.
ComboBoxItem does not provide built-in support for multiple selection. For a Combobox that does provide such a multiple-select feature use MultiComboBoxItem.

`ListGridRecord[]`	`filterClientPickListData()` Returns the data to display in the pick list.
`java.lang.Boolean`	`getAddUnknownValues()` This property controls whether the user can enter a value that is not present in the set of options for this item.
`java.lang.Boolean`	`getAllowEmptyValue()` If `addUnknownValues` is `false`, this property determines whether the user can clear the comboBoxItem value, or whether they are constrained to choosing one of the available options (in which case clearing the text box will simply revert to the last picked value when the user leaves the field).
`java.lang.Boolean`	`getAllowExpressions()` The standard `FormItem.allowExpressions` behavior is always disabled for ComboBoxItem.
`java.lang.Boolean`	`getAnimatePickList()` If true, when the pickList is shown, it will be shown via an animated reveal effect

`ComboBoxItem`	`setSingleClickFolderToggle(boolean singleClickFolderToggle)` When this item is showing a tree-based picker, the default behavior is for folder open-state to be toggled by double-clicking.
`void`	`setSort(SortSpecifier[] sortSpecifiers)` Deprecated. in favor of `setPickListSort(SortSpecifier[])` where full documentation can be read.
`ComboBoxItem`	`setSortField(java.lang.Integer sortField)` Specifies one or more fields by which this item should be initially sorted.
`ComboBoxItem`	`setSortField(java.lang.String... sortField)` Specifies one or more fields by which this item should be initially sorted.
`ComboBoxItem`	`setSortField(java.lang.String sortField)` Specifies one or more fields by which this item should be initially sorted.
`void`	`setSpecialValues(java.util.LinkedHashMap valueMap)` Set the specialValues for this item.
`void`	`setSpecialValues(java.lang.String... values)` Set the specialValues for this item.
`ComboBoxItem`	`setTextMatchStyle(TextMatchStyle textMatchStyle)` When applying filter criteria to pickList data, what type of matching to use.
`ComboBoxItem`	`setUseClientFiltering(java.lang.Boolean useClientFiltering)` For `databound` items, this property will be passed to the generated ResultSet data object for the pickList as `ResultSet.useClientFiltering`.
`ComboBoxItem`	`setValueField(java.lang.String valueField)` If this form item maps data values to display values by retrieving the `FormItem.displayField` values from an `optionDataSource`, this property denotes the the field to use as the underlying data value in records from the optionDataSource. If not explicitly supplied, the valueField name will be derived as described in `FormItem.getValueFieldName()`.
`void`	`setValueIconField(java.lang.String valueIconField)` For Databound formItems, this property determines which column `valueIcons` should show up in for this formItem's pickList. If unset valueIcons show up in the `displayField` column if specified, otherwise the `valueField` column. In most cases only the `displayField` or `valueField` will be visible.
`java.lang.Boolean`	`shouldGenerateExactMatchCriteria()` When a comboBoxItem is used to generate search criteria in a SearchForm, if the user explicitly chose an option from the pickList, should the criterion generated by the `FormItemCriterionGetter`'s `getCriterion()` method enforce a search for an exact match against the chosen value?

  - setAddUnknownValues
```
public ComboBoxItem setAddUnknownValues(java.lang.Boolean addUnknownValues)
```
    This property controls whether the user can enter a value that is not present in the set of options for this item.
    If set to false, the value the user enters in the text box is essentially used to filter the set of options displayed in the pickList.
    In this mode, when focus is taken from the field, if the entered value does not match any entries in the com.smartgwt.client.types.ValueMap or optionDataSource, it will be discarded. Note that in this mode, completeOnTab behavior is automatically enabled so if the user enters a valid partial value such that one or more options is displayed in the pickList, and hits the Tab key, the first matching option will be chosen automatically. In this mode the user may also hit the "Escape" key to discard their edits.
    Note also that when addUnknownValues is set to false, the underlying value returned by getValue() will not be updated until a value is explicitly chosen. This means any change or changed handlers will not fire directly in response to the user typing in the field - they will fire when the user actually selects a value, or takes focus from the field.
    If this property is set to true, the user is not limited to entering values present in the set of options for the item. Instead the set of options essentially become a set of suggestions that may be used, or the user can enter an entirely new value.
    
    Parameters:
    
    addUnknownValues - New addUnknownValues value. Default value is true
    
    Returns:
    
    ComboBoxItem instance, for chaining setter calls
  - getAddUnknownValues

    Returns:
    
    Current addUnknownValues value. Default value is true
  - setAllowEmptyValue
```
public ComboBoxItem setAllowEmptyValue(java.lang.Boolean allowEmptyValue)
```
    If addUnknownValues is false, this property determines whether the user can clear the comboBoxItem value, or whether they are constrained to choosing one of the available options (in which case clearing the text box will simply revert to the last picked value when the user leaves the field).
    See also specialValues as a way of providing several different special values in addition to an empty value, such as "Invalid". Note that setting specialValues disables the use of allowEmptyValue - see details of how to have an empty value while using specialValues in in the specialValues documentation.
    
    Parameters:
    
    allowEmptyValue - New allowEmptyValue value. Default value is true
    
    Returns:
    
    ComboBoxItem instance, for chaining setter calls
  - getAllowEmptyValue
```

    Returns:
    
    Current allowEmptyValue value. Default value is true
  - setAllowExpressions
```
public ComboBoxItem setAllowExpressions(java.lang.Boolean allowExpressions)
```
    The standard FormItem.allowExpressions behavior is always disabled for ComboBoxItem.
    The interface is not compatible with the allowExpressions feature. A ComboBoxItem normally starts fetching matches as you type, and that mixes very strangely with the idea of entering expressions like "a..b" - you will have the ComboBox seemingly switching back and forth between treating the text as a normal search string vs as a special expression on a per-keystroke basis.
    We recommend a normal TextItem as the correct UI element to supply for users to enter filter expressions.
    
    Overrides:
    
    setAllowExpressions in class FormItem
    
    Parameters:
    
    allowExpressions - New allowExpressions value. Default value is null
    
    Returns:

  - setAutoOpenTree
```
public ComboBoxItem setAutoOpenTree(java.lang.String autoOpenTree)
```
    When this item is showing a tree-based picker, which nodes should be opened automatically. Options are:
    - "none" - no nodes are opened automatically
    - "root" - opens the top-level node - in databound tree-pickers, this node is always hidden
    - "all" - when loading data on demand, opens the top-level node and all of it's direct descendants - otherwise, opens all loaded nodes
    Parameters:
    
    autoOpenTree - New autoOpenTree value. Default value is "none"
    
    Returns:
    
    ComboBoxItem instance, for chaining setter calls

  - setCachePickListResults
```
public ComboBoxItem setCachePickListResults(boolean cachePickListResults)
```
    For databound pickLists (see PickList.optionDataSource), by default Smart GWT will cache and re-use datasets shown by different pickLists displayed by different SelectItems in an LRU (least recently used) caching pattern.
    Setting this flag to false avoids this caching for situations where it is too aggressive.
    Note that this does not control re-use of data within a single pickList. To control when client-side filtering is used in ComboBoxItem, see useClientFiltering and filterLocally.
    
    Parameters:
    
    cachePickListResults - New cachePickListResults value. Default value is true
    
    Returns:

    Returns:
    
    Current defaultToFirstOption value. Default value is false
  - getDefaultValue
```
public java.lang.Object getDefaultValue()

    Static default value for this ComboBoxItem. To default to the first option use defaultToFirstOption instead.
    
    Returns:
    
    Current defaultValue value. Default value is null
  - setDisplayField
```
public ComboBoxItem setDisplayField(java.lang.String displayField)
```
    If set, this item will display a value from another field to the user instead of showing the underlying data value for the field name.
    This property is used in two ways:
    The item will display the displayField value from the record currently being edited if FormItem.useLocalDisplayFieldValue is true, (or if unset and the conditions outlined in the documentation for that property are met).
    If this field has an FormItem.optionDataSource, this property is used by default to identify which value to use as a display value in records from this related dataSource. In this usage the specified displayField must be explicitly defined in the optionDataSource to be used - see getDisplayFieldName() for more on this behavior.
    If not using local display values, the display value for this item will be derived by performing a fetch against the option dataSource to find a record where the value field matches this item's value, and use the displayField value from that record.
    In addition to this, PickList-based form items that provide a list of possible options such as the SelectItem or ComboBoxItem will show the displayField values to the user by default, allowing them to choose a new data value (see FormItem.valueField) from a list of user-friendly display values.
    This essentially allows the specified optionDataSource to be used as a server based valueMap.
    If local display values are being used and FormItem.storeDisplayValues is true, selecting a new value will update both the value for this field and the associated display-field value on the record being edited.
    Note: Developers may specify the FormItem.foreignDisplayField property in addition to displayField. This is useful for cases where the display field name in the local dataSource differs from the display field name in the optionDataSource. See the documentation for DataSourceField.foreignDisplayField for more on this.
    If a foreignDisplayField is specified, as with just displayField, if local display values are being used and FormItem.storeDisplayValues is true, when the user chooses a value the associated display-field value on the record being edited will be updated. In this case it would be set to the foreignDisplayField value from the related record. This means foreignDisplayField is always expected to be set to the equivalent field in the related dataSources.
    Developers looking to display some other arbitrary field(s) from the related dataSource during editing should consider using custom PickList.pickListFields instead of setting a foreignDisplayField.
    Note that if optionDataSource is set and no valid display field is specified, FormItem.getDisplayFieldName() will return the dataSource title field by default.
    If a displayField is specified for a freeform text based item (such as a ComboBoxItem), any user-entered value will be treated as a display value. In this scenario, items will derive the data value for the item from the first record where the displayField value matches the user-entered value. To avoid ambiguity, developers may wish to avoid this usage if display values are not unique.

    Returns the displayField for this item.
    Behavior varies based on the configuration of this item, as follows:
    If this item has an optionDataSource and an explicit FormItem.foreignDisplayField is specified, this will be returned.
    
    Otherwise if an explicit displayField is specified it will be returned by default. If the displayField was specified on the underlying dataSource field, and no matching field is present in the optionDataSource for the item, we avoid returning the specified displayField value and instead return the title field of the option DataSource. We do this to avoid confusion for the case where the displayField is intended as a display-field value for showing another field value within the same record in the underlying dataSource only.
    
    If no explicit foreignDisplay or displayField specification was found, and the FormItem.valueField for this item is hidden in the FormItem.optionDataSource, this method will return the title field for the optionDataSource.

  - setFetchDisplayedFieldsOnly
```
public ComboBoxItem setFetchDisplayedFieldsOnly(java.lang.Boolean fetchDisplayedFieldsOnly)
```
    If this item has a specified optionDataSource and this property is true, the list of fields used by this pickList will be passed to the datasource as DSRequest.outputs. If the datasource supports this feature the returned fields will be limited to this list. A custom datasource will need to add code to implement field limiting.
    This list of used fields consists of the values of valueField, displayField and pickListFields.
    NOTE: When enabled, getSelectedRecord will only include the fetched fields.
    Note : This is an advanced setting
    
    Parameters:

  - setFilterFields
```
public ComboBoxItem setFilterFields(java.lang.String... filterFields)
```
    As the user types into this item's textBox, a comboBoxItem will show the pick-list of options, and filter the set of results displayed by the current value in the text box. For a databound comboBoxItem, by default the entered value is filtered against the displayField if one is specified, otherwise the valueField.
    This attribute allows the developer to explicitly change which fields to filter against, causing the user-entered text to be matched against any of the specified set of fields from the optionDataSource.
    This essentially causes getPickListFilterCriteria() to return an AdvancedCriteria object representing "field1 starts with value or field2 starts with value or ...". The operator used is controlled by TextMatchStyle as usual, that is, "startsWith" implies the operator "iStartsWith, "substring" implies "iContains" and "exact" implies "iEquals".
    The most common use case for this setting would be when a comboBoxItem is showing multiple pickListFields - if the same set of fields is specified as filterFields, the user can use the text-box to filter against whichever fields are visible in the pickList.
    For finer grained control over comboBoxItem filtering, the comboBoxItem.setPickListFilterCriteriaFunction() may be specified.
    
    Parameters:
    
    filterFields - New filterFields value. Default value is null
    
    Returns:
    
    ComboBoxItem instance, for chaining setter calls

  - setFilterLocally
```
public ComboBoxItem setFilterLocally(java.lang.Boolean filterLocally)
```
    If filterLocally is set for this item, and this item is showing options from a dataSource, fetch the entire set of options from the server, and use these values to map the item value to the appropriate display value. Also use "local" type filtering on drop down list of options.
    This means data will only be fetched once from the server, and then filtered on the client.
    Note - when this property is set to false, filtering will still be performed on the client if a complete set of data for some criteria has been cached by a fetch, and a subsequent fetch has more restrictive criteria. To explicitly disable client-side filtering set the useClientFiltering property to false.
    Note : This is an advanced setting
    
    Specified by:
    
    setFilterLocally in interface PickList
    
    Overrides:

  - setFormatOnBlur
```
public ComboBoxItem setFormatOnBlur(java.lang.Boolean formatOnBlur)
```
    With formatOnBlur enabled, this comboBoxItem will format its value according to the rules described in FormItem.mapValueToDisplay() as long as the item does not have focus. Once the user puts focus into the item the formatter will be removed. This provides a simple way for developers to show a nicely formatted display value in a freeform text field, without the need for an explicit FormItem.formatEditorValue() and FormItem.parseEditorValue() pair.
    Note that this attribute is not compatible with completeOnTab
    
    Overrides:
    
    setFormatOnBlur in class TextItem
    
    Parameters:

  - setGenerateExactMatchCriteria
```
public ComboBoxItem setGenerateExactMatchCriteria(java.lang.Boolean generateExactMatchCriteria)
```
    When a comboBoxItem is used to generate search criteria in a SearchForm this property governs whether, if the user explicitly chose an option from the pickList, we explicitly generate criteria that will search for an exact match against the chosen value.
    In order to achieve this, when this property is set to true, this item will generate AdvancedCriteria in the default FormItemCriterionGetter's getCriterion() method.
    See shouldGenerateExactMatchCriteria() for behavior when this flag is unset.
    Note : This is an advanced setting
    
    Parameters:

public ComboBoxItem setPendingTextBoxStyle(java.lang.String pendingTextBoxStyle)
```
    Optional "pending" style for this item's text box.
    If addUnknownValues is false, when the user modifies the value displayed in the combobox item text box, the underlying data value (as returned from item.getValue()) is not immediately updated - instead the value is used to filter the set of results displayed in the comboBoxItem pickList.
    While the comboBoxItem is in this pending state (where the result of getEnteredValue() will not necessarily match the display value for whatever is returned by getValue()), the pendingTextBoxStyle may be applied to the text box for the item.
    When the element value is updated to display the actual value for the item (typically due to the user selecting a value from the pickList), the standard TextItem.textBoxStyle will be reapplied.
    May be left unset in which case the standard text box style is always applied. Has no effect if addUnknownValues is true.
    
    Parameters:
    
    pendingTextBoxStyle - New pendingTextBoxStyle value. Default value is null
    
    Returns:
    
    ComboBoxItem instance, for chaining setter calls

  - fetchData
```
public void fetchData()
```
    Only applies to databound items (see PickList.optionDataSource).
    Performs a fetch type operation on this item's DataSource to retrieve the set of valid options for the item, based on the current PickList.pickListCriteria.
  - fetchData
```
public void fetchData(DSCallback callback)

    fetchData()
  - fetchData
```
public void fetchData(DSCallback callback,
                      DSRequest requestProperties)
```
    Only applies to databound items (see PickList.optionDataSource).
    Performs a fetch type operation on this item's DataSource to retrieve the set of valid options for the item, based on the current PickList.pickListCriteria.
    Parameters:
    callback - Callback to fire when the fetch completes. Callback will fire with 4 parameters:
    
    item a pointer to the form item
    dsResponse the DSResponse returned by the server
    data the raw data returned by the server
    dsRequest the DSRequest sent to the server
    requestProperties - properties to apply to the dsRequest for this fetch.
  - filterClientPickListData
```
public ListGridRecord[] filterClientPickListData()
```
    Returns the data to display in the pick list.
    The default implementation applies the criteria returned by PickList.getPickListFilterCriteria() to the data returned by PickList.getClientPickListData(). A record passes the filter if it has a matching value for all fields in the criteria object. Matching is performed according to TextMatchStyle.
    If PickList.showAllOptions is set, all values are shown, with matching values shown below a separator.
    
    Specified by:
    
    filterClientPickListData in interface PickList
    
    Returns:
    
    array of record objects to display in the pickList
  - getClientPickListData
```
public ListGridRecord[] getClientPickListData()
```
    Returns the set of data to be displayed in this item's PickList.
    This method will be called for non-databound form items implementing the PickList interface. The default implementation will derive data from the item's valueMap - can be overridden to allow a custom set of options to be displayed.
    Note that for PickLists that filter data based on user input (ComboBox), this method should return the data before filtering. To customize the data returned after filtering, override filterClientPickListData() instead.
    As an example, for a formItem with valueField set to "valueFieldName", the default implementation would take a valueMap like the following:
```
      valueMap: { value1: "display 1", value2: "display 2" }
  
```
    .. and returning the following set of records:
```
      [
           { valueFieldName : "value1" },
           { valueFieldName : "value2" }
      ]
  
```
    Due to the valueMap, these records will appear as a two row pickList displayed as "display 1" and "display 2".
    Specified by:
    
    getClientPickListData in interface PickList
    
    Returns:
    
    Array of record objects to be displayed in the pickList. Note that when a user picks a record from the list, the value of the field matching item.valueField will be picked. Also note that the fields to be displayed can be customized via item.pickListFields
  - getDisplayFieldName
```
public java.lang.String getDisplayFieldName()
```
    Returns the displayField for this item.
    Behavior varies based on the configuration of this item, as follows:
    - If this item has an optionDataSource and an explicit FormItem.foreignDisplayField is specified, this will be returned.
    - Otherwise if an explicit displayField is specified it will be returned by default. If the displayField was specified on the underlying dataSource field, and no matching field is present in the optionDataSource for the item, we avoid returning the specified displayField value and instead return the title field of the option DataSource. We do this to avoid confusion for the case where the displayField is intended as a display-field value for showing another field value within the same record in the underlying dataSource only.
    - If no explicit foreignDisplay or displayField specification was found, and the FormItem.valueField for this item is hidden in the FormItem.optionDataSource, this method will return the title field for the optionDataSource.
    Specified by:
    
    getDisplayFieldName in interface PickList
    
    Overrides:
    
    getDisplayFieldName in class FormItem
    
    Returns:
    
    display field name, or null if there is no separate display field to use. See FieldName
  - getEnteredValue
```
public java.lang.String getEnteredValue()
```
    Returns the raw text value that currently appears in the text field, which can differ from FormItem.getValue() in various cases - for example:
    - for items that constrain the value range, such as a DateItem with enforceDate:true, or a ComboBoxItem with addUnknownValues:false
    - for items with a defined valueMap or edit value formatter and parser functions which converts display value to data value
    - while the item has focus if changeOnKeypress is false
    Note: if the pickList is being shown in any view other than the default nearOrigin, as is typically the case on a mobile device, this method will return the value of the pickerSearchField.
    Overrides:
    
    getEnteredValue in class TextItem
    
    Returns:
    
    current entered value
  - getValueFieldName
```
public java.lang.String getValueFieldName()
```
    Getter method to retrieve the FormItem.valueField for this item. For items with a specified FormItem.optionDataSource, this determines which field in that dataSource corresponds to the value for this item.
    If unset, if a foreignKey relationship exists between this field and the optionDataSource, this will be used, otherwise default behavior will return the FormItem.name of this field.
    
    Specified by:
    
    getValueFieldName in interface PickList
    
    Overrides:
    
    getValueFieldName in class FormItem
    
    Returns:
    
    fieldName to use a "value field" in records from this items FormItem.optionDataSource
  - hasAdvancedCriteria
```
public java.lang.Boolean hasAdvancedCriteria()
```
    Will this item return advancedCriteria if DynamicForm.getValuesAsCriteria() is called on this item's form?
    This method is overridden in ComboBoxItem to return true if shouldGenerateExactMatchCriteria() returns true, and the user has chosen an exact value from the options in the pickList. In this case we will use advancedCriteria to ensure the generated search criteria exactly matches the chosen value for this item.
    As with formItem.hasAdvancedCriteria() this will also return true if an Operator was explicitly specified for this item
    See ComboBoxItemCriteria for a discussion of criterion generated by a ComboBoxItem.
    
    Overrides:
    
    hasAdvancedCriteria in class FormItem
    
    Returns:
    
    true if the result of getCriterion() will be an AdvancedCriteria object.
    
    See Also:
    
    CriteriaEditing overview and related methods
  - shouldGenerateExactMatchCriteria
```
public java.lang.Boolean shouldGenerateExactMatchCriteria()
```
    When a comboBoxItem is used to generate search criteria in a SearchForm, if the user explicitly chose an option from the pickList, should the criterion generated by the FormItemCriterionGetter's getCriterion() method enforce a search for an exact match against the chosen value?
    In order to achieve this, when this property is set to true, this item will generate AdvancedCriteria in the default FormItemCriterionGetter's getCriterion() method.
    Default implementation will return generateExactMatchCriteria if specified, otherwise true if the DataSource for this item supports advanced criteria, false if it does not.
    See ComboBoxItemCriteria for a discussion of criterion generated by a ComboBoxItem.
    
    Returns:
    
    should getCriterion() generate exact-match search criteria when a value was explicitly chosen from this item's set of options?
  - setDefaultProperties
```
public static void setDefaultProperties(ComboBoxItem comboBoxItemProperties)
```
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.
    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
    
    Parameters:
    
    comboBoxItemProperties - properties that should be used as new defaults when instances of this class are created
    
    See Also:
    
    SGWTProperties
  - getPickListFilterCriteria
```
protected Criteria getPickListFilterCriteria()
```
    Returns filter criteria for options displayed for this item.
    See ComboBoxFiltering for details on how pickList filter criteria are calculated by default for a comboBoxItem.
    Note : this is an override point - if overridden this method will be called by the live form item during filtering. However it is recommended that developers use setPickListFilterCriteriaFunction(FormItemCriteriaFunction) to build custom criteria instead of overriding this method directly. This ensures that the custom filter criteria generating code will be called even if the form item was automatically generated based on a template passed to ListGridField.setEditorType(com.smartgwt.client.widgets.form.fields.FormItem).
    
    Returns:
    
    criteria to be used for databound or local filtering

    getFetchDelay in interface PickList
    
    Returns:
    
    the fetch delay
  - setOptionDataSource
```
public ComboBoxItem setOptionDataSource(DataSource dataSource)
```
    If set, this FormItem will derive data to show in the PickList by fetching records from the specified optionDataSource. The fetched data will be used as a valueMap by extracting the valueField and displayField in the loaded records, to derive one valueMap entry per record loaded from the optionDataSource. Multiple fields from the fetched data may be shown in the pickList by setting pickListFields.
    The data will be retrieved via a "fetch" operation on the DataSource, passing the pickListCriteria (if set) as criteria, and passing optionFilterContext (if set) as DSRequest properties.
    The fetch will be triggered when the pickList is first shown, or, you can set autoFetchData to fetch when the FormItem is first drawn. You can also call com.smartgwt.client.widgets.form.fields.PickList#fetchData at any time to manually trigger a fetch.
    Data paging is automatically enabled if the optionDataSource supports it. As the pickList is scrolled by the user, requests for additional data will be automatically issued.
    For a pickList attached to a ComboBoxItem, new fetches are issued as the user types, with criteria set as described under getPickListFilterCriteria(). If your dataSource is not capable of filtering results by search criteria (eg the dataSource is backed by an XML flat file), you can set filterLocally to have the entire dataset loaded up front and filtering performed in the browser. This disables data paging.
    Setting optionDataSource also enables the basic optionDataSource behaviors, eg, fetching individual display values before the pickList is shown.
    Note that if a normal, static valueMap is also specified for the field (either directly in the form item or as part of the field definition in the dataSource), it will be preferred to the data derived from the optionDataSource for whatever mappings are present.
    Note : This is an advanced setting
    
    Specified by:
    
    setOptionDataSource in interface PickList
    
    Overrides:
    
    setOptionDataSource in class FormItem
    
    Parameters:
    
    dataSource - optionDataSource Default value is null
    
    Returns:
    
    ComboBoxItem instance, for chaining setter calls
    
    See Also:
    
    FormItem.invalidateDisplayValueCache(), List - Combo Box Example
  - getOptionDataSource
```
public DataSource getOptionDataSource()
```
    Description copied from class: FormItem
    
    If set, this FormItem will map stored values to display values as though a com.smartgwt.client.types.ValueMap were specified, by fetching records from the specified optionDataSource and extracting the valueField and displayField in loaded records, to derive one valueMap entry per record loaded from the optionDataSource.
    With the default setting of fetchMissingValues, fetches will be initiated against the optionDataSource any time the FormItem has a non-null value and no corresponding display value is available. This includes when the form is first initialized, as well as any subsequent calls to setValue(), such as may happen when DynamicForm.editRecord() is called. Retrieved values are automatically cached by the FormItem.
    Note that if a normal, static valueMap is also specified for the field (either directly in the form item or as part of the field definition in the dataSource), it will be preferred to the data derived from the optionDataSource for whatever mappings are present.
    In a databound form, if displayField is specified for a FormItem and optionDataSource is unset, optionDataSource will default to the form's current DataSource
    
    Specified by:
    
    getOptionDataSource in interface PickList
    
    Overrides:
    
    getOptionDataSource in class FormItem
    
    Returns:
    
    Returns the optionDataSource for this item.
    Always uses item.optionDataSource if specified. Otherwise, if DataSourceField.foreignKey was specified, uses the target DataSource. Otherwise, uses the DataSource of this item's form (if one is configured). Default value is null

  - getSelectedRecord
```
public ListGridRecord getSelectedRecord()
```
    Returns the entire record object associated with the current value for this item (or null if no matching record exists in the PickList data). Most commonly used for databound pickListItems to retrieve the values of other fields in the record.
    
    Overrides:
    
    getSelectedRecord in class FormItem
    
    Returns:
    
    the selected record or null
  - setPickListFilterCriteriaFunction
```
public void setPickListFilterCriteriaFunction(FilterCriteriaFunction filterCriteriaFunction)
```
    Deprecated. in favor of setPickListFilterCriteriaFunction(FormItemCriteriaFunction)
    
    Set the pick list filter criteria function / handler.
    
    Specified by:
    
    setPickListFilterCriteriaFunction in interface PickList
    
    Parameters:
    
    filterCriteriaFunction - the filter criteria function
  - setPickListFilterCriteriaFunction
```
public void setPickListFilterCriteriaFunction(FormItemCriteriaFunction filterCriteriaFunction)
```
    Set up a method to return filter criteria for options displayed for this item.
    See ComboBoxFiltering for details on how pickListCriteria are calcualted by default for a ComboBoxItem.
  - setPickListProperties
```
public void setPickListProperties(ListGrid pickListProperties)
```
    Allows developers to designate a PickListMenu as a template containing arbitrary properties to apply to the pickList that will be created for this FormItem.
    Note: Not every PickListMenu / ListGrid property is supported when assigned to a pickList. Where there is a dedicated API on the form item (such as PickList.setPickListCellHeight(int)), we recommend that be used in favor of setting the equivalent property directly using this API.
    PickLists and ListGrid.setShowFilterEditor(boolean): ComboBoxItems do not support setting showFilterEditor to true on pickListProperties. This combination of settings leads to an ambiguous user experience as the two sets of filter-criteria (those from the text-box and those from the pickList filter editor) interact with each other.
    Calling setShowFilterEditor on the PickListMenu passed to SelectItem.setPickListProperties(com.smartgwt.client.widgets.grid.ListGrid) is a valid way to create a filterable pickList, on a SelectItem, but this setting is not supported on a SelectItem with multiple set to true - this combination of settings can cause a selected value to be filtered out of view at which point further selection changes will discard that value.
    In general we recommend the ComboBoxItem class (with addUnknownValues set as appropriate) as a better interface for filtering pickList data.
    
    Parameters:
    
    pickListProperties - the pick list properties
  - setOptionFilterContext
```
public void setOptionFilterContext(DSRequest dsRequestProperties)
```
    Description copied from interface: PickList
    
    If this item has a specified optionDataSource, and this property is not null, this will be passed to the datasource as RPCRequest properties when performing the fetch operation on the dataSource to obtain a data-value to display-value mapping
    Note : This is an advanced setting
    
    Specified by:
    
    setOptionFilterContext in interface PickList
    
    Parameters:
    
    dsRequestProperties - optionFilterContext Default value is null
  - getValueAsString
```
public java.lang.String getValueAsString()
```
    Return the value tracked by this form item.
    
    Overrides:
    
    getValueAsString in class TextItem
    
    Returns:
    
    value of this element
  - setCanEditCriterionPredicate
```
public void setCanEditCriterionPredicate(FormItemCanEditCriterionPredicate predicate)
```
    The default canEditCriterion() predicate is overridden in comboBoxItem. When addUnknownValues is true, comboBoxItems allow the user to edit substring match type criteria applied to the display field (if one is specified).
    The user can also edit criteria attempting to match exactly against the item's field name.
    
    Overrides:
    
    setCanEditCriterionPredicate in class FormItem
    
    Parameters:
    
    predicate - the predicate to determine the form items that can edit the criterion in question
    
    See Also:
    
    FormItem.setCanEditCriterionPredicate, CriteriaEditing overview and related methods
  - setCriterionGetter
```
public void setCriterionGetter(FormItemCriterionGetter getter)
```
    The default getCriterion() implementation returns criterion derived from the current value of this item.
    If addUnknownValues is true for this item, we implement the following behavior.
    If the user explicitly selected an item from the pickList, we treat this as an attempt to explicitly match the data value. In this case returned criteria will match the selected (data) value against this item's fieldName.
    If the user typed a value into the text field, we treat this as an attempt to do a substring type filter. In this case returned criteria will match the entered text value against the displayField for this item if one is specified.
    If addUnknownValues is false we always match the chosen data value against the item's fieldName.
    Note that ComboBoxItem.shouldGenerateExactMatchCriteria will be called in the case when a value was explicitly picked from the set of options. If that method returns true, we will return AdvancedCriteria with an operator specified to ensure an exact match occurs.
    
    Overrides:
    
    setCriterionGetter in class FormItem
    
    Parameters:
    
    getter - provides a method to get a criterion object based on this field's current edited value(s).
    
    See Also:
    
    FormItem.setCriterionGetter(com.smartgwt.client.widgets.form.FormItemCriterionGetter), CriteriaEditing overview and related methods
  - setCriterionSetter
```
public void setCriterionSetter(FormItemCriterionSetter setter)
```
    The default setCriterion() implementation is overridden to support editing criterion against the display field or value field when addUnknownValues is true.
    
    Overrides:
    
    setCriterionSetter in class FormItem
    
    Parameters:
    
    setter - provides a method to update this field with the edited criterion
  - setPickListSort
```
public void setPickListSort(SortSpecifier[] sortSpecifiers)
```
    This method sorts the pickList on one or more fields, creating the underlying JS object if needed. Pass in an array of SortSpecifiers to have the grid's data sorted by the fields in each specifier.property and in the directions specified. The grid can be sorted by any combination of fields, including fields specified in the fields array, whether visible or hidden, and 'unused fields from the underlying dataSource', if there is one. If multiple fields are sorted, those that are visible show a directional icon and a small 'sort-numeral' indicating that field's index in the sort configuration.
    See ListGrid.addSort(com.smartgwt.client.data.SortSpecifier) and com.smartgwt.client.widgets.grid.ListGrid#alterSort APIs for information on making changes to the current sort configuration.
    
    Parameters:
    
    sortSpecifiers - Array of SortSpecifier objects
  - setSort
```
public void setSort(SortSpecifier[] sortSpecifiers)
```
    Deprecated. in favor of setPickListSort(SortSpecifier[]) where full documentation can be read.
    
    Sorts the pickList on one or more fields.
    
    Parameters:
    
    sortSpecifiers - Array of SortSpecifier objects
