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 addUnkownValues 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.

`void`	`fetchData(DSCallback callback, DSRequest requestProperties)` Only applies to databound items (see 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 pickListCriteria.
`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`	`getAnimatePickList()` If true, when the pickList is shown, it will be shown via an animated reveal effect

  - setAddUnknownValues
```
public void 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 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 setting this property to false on a databound ComboBoxItem, data paging should be disabled - this is required since the ComboBoxItem requires all data to be present in order to determine whether an entered value is new. Data Paging can be disabled by modifying the dataFetchMode on the pickListProperties for this item.
    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 - addUnknownValues Default value is true

public void setCachePickListResults(boolean cachePickListResults)
```
    For databound pickLists (see 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:

```
public void setDefaultToFirstOption(java.lang.Boolean defaultToFirstOption)
```
    Select the first option as the default value for this ComboBoxItem. If options are derived from a dataSource, the first value returned by the server will be used, otherwise the first value in the valueMap. If enabled, this setting overrides defaultValue and ComboBoxItem.defaultDynamicValue.
    
    Parameters:
    defaultToFirstOption - defaultToFirstOption Default value is false
  - getDefaultToFirstOption
```
public java.lang.Boolean getDefaultToFirstOption()

  - setDisplayField
```
public void setDisplayField(java.lang.String displayField)
```
    Specifies an alternative field from which display values should be retrieved for this item.
    The display field can be either another field value in the same record or a field that must be retrieved from a related optionDataSource.
    If this item is not databound (optionDataSource is unset), or bound to the same dataSource as the form as a whole, this item will call form.getValue() the form named after is implemented by picking up the value of the specified field from the Form's values object.
    Otherwise this item will attempt to map its underlying value to a display value by retrieving a record from the optionDataSource where the valueField matches this item's value, and displaying the displayField value from that record. Note that if optionDataSource is set and this value is not set, FormItem.getDisplayFieldName will return the dataSource title field by default.
    This essentially enables the specified optionDataSource to be used as a server based valueMap.

  - setFetchDisplayedFieldsOnly
```
public void 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 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:
    fetchDisplayedFieldsOnly - fetchDisplayedFieldsOnly Default value is null
  - getFetchDisplayedFieldsOnly

    Returns:
    Boolean
  - setFilterFields
```
public void 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 ComboBoxItem.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 criteriaFields, 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 setPickListFilterCriteriaFunction may be specified.
    
    Parameters:
    filterFields - . See String. Default value is null
  - getFilterFields

  - setFilterLocally
```
public void 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.

    With formatOnBlur enabled, this item will format its value according to any specified static static formatter 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 simply 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.

  - setPendingTextBoxStyle
```
public void 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 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.

  - hasAdvancedCriteria
```
public java.lang.Boolean hasAdvancedCriteria()
```
    Will this item return advancedCriteria if DynamicForm.getValuesAsCriteria is called on this item's form? Overridden for ComboBoxItem to return true if generateExactMatchCriteria is true - in this case if an exact value is chosen from our set of options (always the case if addUnkownValues is false), we will use advancedCriteria to ensure the generated search criteria exactly matches the chosen value for this item.
    Note that AdvancedCriteria are not supported by all dataSources. When a form is bound to a dataSource, we therefore default generateExactMatchCriteria to false unless the dataSource is known to support AdvancedCriteria.
    As with formItem.hasAdvancedCriteria() this will also return true if a Operator was explicitly specified for this item
    
    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.
    
    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 subsequent instances of this class will automatically have the default properties that were set when this method was called. 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 effect 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.
    
    Parameters:
    comboBoxItemProperties - properties that should be used as new defaults when instances of this class are created
  - 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
  - setPickListHeight
```
public void setPickListHeight(int pickListHeight)

    getPickListHeaderHeight in interface PickList
    
    Returns:
    int
  - setValueIconField
```
public 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. This property is typically only required if custom pickListFields have been specfied for this item.
    Note : This is an advanced setting
    
    Specified by:
    
    setValueIconField in interface PickList
    
    Parameters:
    valueIconField - valueIconField Default value is null
  - getValueIconField

  - setFetchDelay
```
public void setFetchDelay(java.lang.Integer fetchDelay)
```
    Description copied from interface: PickList
    
    For a ComboBox or other pickList that accepts user-entered criteria, how many millseconds to wait after the last user keystroke before fetching data from the server. The default setting will initiate a fetch if the stops typing or pauses briefly.
    
    Specified by:
    
    setFetchDelay in interface PickList
    
    Parameters:
    fetchDelay - the fetch delay. defaults to 200ms
  - getFetchDelay
```
public java.lang.Integer getFetchDelay()
```
    Description copied from interface: PickList
    
    For a ComboBox or other pickList that accepts user-entered criteria, how many millseconds to wait after the last user keystroke before fetching data from the server. The default setting will initiate a fetch if the stops typing or pauses briefly.
    
    Specified by:
    
    getFetchDelay in interface PickList
    
    Returns:
    the fetch delay
  - getSortFieldAsInt
```
public java.lang.Integer getSortFieldAsInt()
```
    Specifies the field by which this item should be initially sorted. Can be set to either a 'field name' or the index of the field in the fields Array. Note that if sortField is initally specified as a number, it will be converted to a string (field name) after the item is initialized.
    To programmatically change sort field or direction after initialization, call ${isc.DocUtils.linkForRef('sort')}.
    
    Returns:
    Integer
  - setOptionDataSource
```
public void 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
  - getOptionDataSource
```
public DataSource getOptionDataSource()
```
    Specified by:
    
    getOptionDataSource in interface PickList
  - setSeparatorRows
```
public void setSeparatorRows(ListGridRecord[] separatorRows)
```
    Array of records to show between matching and non-matching rows in the PickList.
    Not valid for optionDataSource.
    
    Specified by:
    
    setSeparatorRows in interface PickList
    
    Parameters:
    separatorRows - separatorRows Default value is [{isSeparator:true}]
  - filterClientPickListData
```
public ListGridRecord[] filterClientPickListData()
```
    Description copied from interface: PickList
    
    Returns the data to display in the pick list.
    The default implementation applies the criteria returned by #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 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()
```
    Description copied from interface: PickList
    
    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.
    
    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
  - setPickListFields
```
public void setPickListFields(ListGridField... pickListFields)
```
  - 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)
```
    Set the properties to be applied to the pickList created for this Form Item.
    
    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
