public class ComboBoxItem extends TextItem implements PickList, HasDataArrivedHandlers
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:
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.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.

public ComboBoxItem setAddUnknownValues(java.lang.Boolean addUnknownValues)
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.

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.

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.

 present in the optionDataSource for

 DataSource. We do this to  avoid confusion for the case where the displayField is intended as a display-field  value for

public ComboBoxItem setFilterFields(java.lang.String... filterFields)
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".

 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 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.
filterClientPickListData in interface PickListpublic ListGridRecord[] getClientPickListData()
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".getClientPickListData in interface PickListitem.valueField will be picked. Also note that the          
 fields to be displayed can be customized via item.pickListFieldspublic java.lang.String getDisplayFieldName()
displayField for this item. Behavior varies based on the configuration of this item, as follows:
optionDataSource and an explicit   FormItem.foreignDisplayField is specified, this will be returned.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.FormItem.valueField for this item is hidden in the  
 FormItem.optionDataSource, this method will
 return the title field for   the optionDataSource.getDisplayFieldName in interface PickListgetDisplayFieldName in class FormItemFieldNamepublic java.lang.String getEnteredValue()

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

public static void setDefaultProperties(ComboBoxItem comboBoxItemProperties)
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.
comboBoxItemProperties - properties that should be used as new defaults when instances of this class are createdSGWTPropertiesprotected Criteria getPickListFilterCriteria()
 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).

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.

 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

 as a template containing arbitrary properties to apply to the pickList that will be

 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.

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.
