`void`	`setValues(java.lang.String... values)` Set the values of a SelectItem with multiple=true.
`void`	`showPicker()` Method to show a picker for this item.

```
    Changes the defaults for Canvas AutoChildren named autoChildName.
    
    Parameters:
    
    autoChildName - name of an AutoChild to customize the defaults for.
    
    defaults - Canvas defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, see SGWTProperties.

  - setAddUnknownValues
```
public SelectItem setAddUnknownValues(java.lang.Boolean addUnknownValues)
```
    If this item's value is set (via setValue() or similar) to a value which is not present in the com.smartgwt.client.types.ValueMap, should the value be rejected.
    If set to false the setValue() call will have no effect if the value is not a valid option.
    If set to true the item's value will be updated to the new value, and the value will be added to the set of options displayed in the pick-list until the next call to setValueMap() or setValue().
    Exception: If the value is set to null but there is no null entry in the valueMap for this item, setting addUnknownValues to true will not cause a null option to show up at the top of the select item pickList. Whether an empty option is shown in the pickList is governed by allowEmptyValue instead.
    Note that this property has no effect if the selectItem has a specified optionDataSource. If setValue() is called on a databound SelectItem and the new value does not match any loaded options, the value will be accepted, but not added to the options displayed in the pickList. Also note that if a displayField exists, a fetch will be performed in an attempt to retrieve a valid display value, as described under FormItem.fetchMissingValues. If specified the FormItem.loadingDisplayValue will be displayed while the fetch is in progress, and then the real value (mapped to a display field value if a matching record was found) will be displayed when the fetch completes.
    Note : This is an advanced setting
    
    Parameters:
    
    addUnknownValues - New addUnknownValues value. Default value is true
    
    Returns:

  - setAllowEmptyValue
```
public SelectItem setAllowEmptyValue(java.lang.Boolean allowEmptyValue)
```
    If set to true, always show an empty option in this item's pickList, allowing the user to clear the value (even if there is no empty entry in the valueMap for the item).
    The empty value will be displayed with the emptyDisplayValue.
    With a databound selectItem, enabling allowEmptyValue disables data paging by default - all data matching the current criteria will be requested. However, enabling separateSpecialValues allows data paging to be used if required.
    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 false
    
    Returns:
    
    SelectItem instance, for chaining setter calls
  - getAllowEmptyValue

    Returns:
    
    Current allowEmptyValue value. Default value is false
  - setAllowMultiCharSearch
```
public SelectItem setAllowMultiCharSearch(boolean allowMultiCharSearch)
```
    By default, if multiple keys are pressed in quick succession, a SelectItem will buffer them together and use the resulting multi-char string when searching. Set this attribute to false to force the item to match only one character at a time.
    
    Parameters:
    
    allowMultiCharSearch - New allowMultiCharSearch value. Default value is true
    
    Returns:
    
    SelectItem instance, for chaining setter calls

  - setAutoFetchData
```
public SelectItem setAutoFetchData(java.lang.Boolean autoFetchData)
```
    If this select item retrieves its options from a dataSource, should options be fetched from the server when the item is first drawn, or should this fetch be delayed until the user opens the pickList.
    The default is true in order to allow the user to select a value via keyboard input while keyboard focus is on the SelectItem but the pickList has not actually been shown.
    Note : This is an advanced setting
    
    Parameters:
    
    autoFetchData - New autoFetchData value. Default value is true
    
    Returns:

  - setAutoOpenTree
```
public SelectItem 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:
    
    SelectItem instance, for chaining setter calls

  - setCachePickListResults
```
public SelectItem setCachePickListResults(java.lang.Boolean cachePickListResults)
```
    For databound pickLists (see PickList.optionDataSource), by default Smart GWT will cache and re-use datasets shown by pickLists in an LRU (least recently used) caching pattern.
    Setting this flag to false avoids this caching for situations where it is too aggressive.
    
    Parameters:
    
    cachePickListResults - New cachePickListResults value. Default value is true
    
    Returns:
    
    SelectItem instance, for chaining setter calls
  - getCachePickListResults

    Overrides:
    
    getCanSelectText in class FormItem
    
    Returns:
    
    Current canSelectText value. Default value is false
  - setClickMaskMode
```
public SelectItem setClickMaskMode(ClickMaskMode clickMaskMode)
```
    Determines the behavior of the click-mask thrown up when this pickList is visible.
    The default value, "hard", matches the familiar behavior of combos and selects on Windows, Mac and other platforms - mouse-events such as rollovers are blocked and, when a click is received, the picker is hidden and the event is cancelled.
    When clickMaskMode is "soft", mouse-events continue to fire, meaning that rollover styles, for example, continue to be updated. When a click is received in this mode, the picker is hidden and the click event is allowed to proceed to its target - this means that clicking an item with an open picker will re-open the picker.
    
    Parameters:
    
    clickMaskMode - New clickMaskMode value. Default value is "hard"
    
    Returns:
    
    SelectItem instance, for chaining setter calls

    Returns:
    
    Current clickMaskMode value. Default value is "hard"
  - setControlStyle
```
public SelectItem setControlStyle(java.lang.String controlStyle)
```
    Base CSS class name for a form item's "control box". This is an HTML element which contains the text box and picker icon for the item.
    See FormItem.alwaysShowControlBox for details on when the control box is written out.

  - setDataSetType
```
public SelectItem setDataSetType(java.lang.String dataSetType)
```
    Whether to show the picker as a flat list, or a collapsible tree.
    The default value, "list", will use an instance of the pickListConstructor as the picker - "tree" will show an instance of pickTreeConstructor.
    
    Parameters:
    
    dataSetType - New dataSetType value. Default value is "list"
    
    Returns:
    
    SelectItem instance, for chaining setter calls

    If options are derived from a dataSource, the first value returned by the server will be used, otherwise the first value in the valueMap. Note that setting this property to true will trigger a fetch at soon as the form is created, because the form will try to establish a default value at that time.
    If enabled, this setting overrides defaultValue and defaultDynamicValue().
    
    Returns:
    
    Current defaultToFirstOption value. Default value is false
  - getDefaultValue
```
public java.lang.Object getDefaultValue()
```
    Static default value for this SelectItem. To default to the first option use defaultToFirstOption instead.
    
    Overrides:
    
    getDefaultValue in class FormItem
    
    Returns:
    
    Current defaultValue value. Default value is null

  - setDisplayField
```
public SelectItem 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.

    Overrides:
    
    getDisplayField in class FormItem
    
    Returns:
    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.

```
public SelectItem setEscapeHTML(java.lang.Boolean escapeHTML)
```
    By default HTML values in a selectItem will be interpreted by the browser. Setting this flag to true will causes HTML characters to be escaped, meaning the raw value of the field (for example "<b>AAA</b>") is displayed to the user rather than the interpreted HTML (for example "AAA")

public SelectItem 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:
    
    fetchDisplayedFieldsOnly - New fetchDisplayedFieldsOnly value. Default value is null

  - setFilterLocally
```
public SelectItem 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

    Parameters:
    
    initialSort - New initialSort value. Default value is null
    
    Returns:
    
    SelectItem instance, for chaining setter calls

  - setMultiple
```
public SelectItem setMultiple(java.lang.Boolean multiple)
```
    If true, multiple values may be selected.
    The SelectItem will either render as a drop-down allowing multiple selections, or a multi-row list of options similar to a small headerless ListGrid, based on the MultipleAppearance setting.
    The logical value of the formItem, as retrieved by getValue() and set via setValue(), is an Array of Strings reflecting the selected values.
    When this value is true, we disable doubleClick events by default, instead issuing two single clicks by forcibly setting noDoubleClicks: true. If you need to work with doubleClick events, you can disable this default behavior by explicitly setting formItem.pickListProperties.noDoubleClicks: false.
    Note: multiple:true SelectItems with multipleAppearance:"grid" do not currently support optionDataSource binding. You can get around this by calling DataSource.fetchData() directly and calling dsResponse.data.getValueMap() to obtain a valueMap.
    If the multiple attribute is not explicitly specified, it will default to false, unless thie item has a specified valueMap and is part of a filter interface with SearchForm.useMultiSelectForValueMaps set to true.
    
    Overrides:

    Should we show a special 'picker' icon for this form item? Picker icons are customizable via pickerIconProperties. By default they will be rendered inside the form item's "control box" area. By default clicking the pickerIcon will call FormItem.showPicker().
    
    Overrides:
    
    setShowPickerIcon in class FormItem
    
    Parameters:
    
    showPickerIcon - New showPickerIcon value. Default value is true
    
    Returns:
    
    SelectItem instance, for chaining setter calls

  - setSingleClickFolderToggle
```
public SelectItem setSingleClickFolderToggle(boolean singleClickFolderToggle)
```

    Note: when set to true, users can only choose leaf-nodes, since clicking folders would simply toggle them.
    
    Parameters:
    
    singleClickFolderToggle - New singleClickFolderToggle value. Default value is false
    
    Returns:
    
    SelectItem instance, for chaining setter calls

  - setSpecialValues
```
public SelectItem setSpecialValues(java.util.Map specialValues)
```
    A set of "special" values such as "All", "None" or "Invalid" that do not appear in the normal com.smartgwt.client.types.ValueMap or in the data returned by the optionDataSource.
    Like other uses of com.smartgwt.client.types.ValueMap, either a list of values or a mapping from stored to display value can be provided.
    These values can either be shown at the top of the list of values (in the order specified), or can be shown in a separate, non-scrolling region - the setting separateSpecialValues controls this. Note that data paging can only be used if separateSpecialValues is enabled.
    If specialValues are configured, allowEmptyValue is ignored - an empty value, if desired, must be included in the specialValues. To provide a specialValue which clears the value of the field, use the special constant emptyStoredValue.
    specialValues can also be used to take a value that does appear in the normal data and redundantly display it at the top of the list to make it more accessible. Note that in this case it is expected that the special value appears both at the top of the list and in it's normal position in the list, so this works best with separateSpecialValues mode enabled.
    Also, if an optionDataSource is used, specialValues that appear in the normal dataset will be updated by automatic cache synchronization (if the displayField is updated). However when using a distinct valueField and displayField, you are required to provide specialValues as a map (there is no support for fetchMissingValues automatically fetching appropriate display values).
    Note that specialValues are not supported in conjunction with MultiComboBoxItem. Whereas with selectItem.multiple:true, specialValues will never be normal values that may be selected. So, specialValues should have options such as "Select All", "Select None" and others.
    
    Parameters:
    
    specialValues - New specialValues value. Default value is null
    
    Returns:
    
    SelectItem instance, for chaining setter calls
  - getSpecialValues

  - addDataArrivedHandler
```
public com.google.gwt.event.shared.HandlerRegistration addDataArrivedHandler(DataArrivedHandler handler)

  - defaultDynamicValue
```
public java.lang.Object defaultDynamicValue(FormItem item,
                                            DynamicForm form,
                                            java.util.Map values)
```
    Expression evaluated to determine the defaultValue when no value is provided for this item. To default to the first option use defaultToFirstOption instead.
    
    Parameters:
    
    item - the form item itself (also available as "this")
    
    form - the managing DynamicForm instance
    
    values - the current set of values for the form as a whole
    
    Returns:
    
    dynamically calculated default value for this item
  - 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

    For a SelectItem with an optionDataSource and allowing multiple selection (via multiple:true), returns the list of currently selected records, or null if none are selected.
    
    Returns:
    
    the list of selected records, or null if none are selected
  - 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:

                                    boolean pendingStatus,
                                    java.lang.Object newValue,
                                    java.lang.Object value)
```
    Notification method called when showPending is enabled and this SelectItem should either clear or show its pending visual state.
    The default behavior is that the titleStyle and cellStyle are updated to include/exclude the "Pending" suffix. In addition, a multiple SelectItem when displayed in the pending state will apply FormItem.editPendingCSSText to any new value in the text box and also append "Pending" to the cells' ListGrid.baseStyle for cells in the pickList menu corresponding to new values. Returning false will cancel this default behavior.
    
    Parameters:
    
    form - the managing DynamicForm instance.
    
    item - the form item itself (also available as "this").
    
    pendingStatus - true if the item should show its pending visual state; false otherwise.
    
    newValue - the current form item value.
    
    value - the value that would be restored by a call to DynamicForm.resetValues().
    
    Returns:
    
    false to cancel the default behavior.
  - showPicker
```
public void showPicker()
```
    Method to show a picker for this item. By default this method is called if the user clicks on a pickerIcon. May also be called programmatically.
    Overridden from the default FormItem.showPicker() implementation to show the PickList
    
    Overrides:
    
    showPicker in class FormItem
  - setDefaultProperties
```
public static void setDefaultProperties(SelectItem selectItemProperties)
```
    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:
    
    selectItemProperties - properties that should be used as new defaults when instances of this class are created
    
    See Also:
    
    SGWTProperties
  - getPickListFilterCriteria
```
protected Criteria getPickListFilterCriteria()
```
    Returns a set of filter criteria to be applied to the data displayed in the pickList when it is shown.
    If this is a databound item, the criteria will be passed as criteria to DataSource.fetchData(). Otherwise an equivalent client-side filter will be performed on the data returned by PickList.getClientPickListData().
    By default returns PickList.pickListCriteria if specified, otherwise an empty set of criteria so all records will be displayed. 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

```
public void setPickListHeight(int pickListHeight)

  - setPickListCriteria
```
public void setPickListCriteria(DSRequest optionFilterContext)
```
    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 filter operation on the dataSource to obtain the set of options for the list.
    Note : This is an advanced setting
    
    Parameters:
    
    optionFilterContext - optionFilterContext Default value is null
  - setOptionDataSource
```
public SelectItem 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 ComboBoxItem.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:
    
    optionDataSource - optionDataSource Default value is null
    
    Returns:
    
    SelectItem 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

    Parameters:
    
    defaultValues - the defaultValues. Default value is null
  - 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
  - getValues
```
public java.lang.String[] getValues()
```
    Returns the values of a SelectItem with multiple=true as an array of Strings.
    
    Returns:
    
    value of selection. If no values are selected, and empty array is returned
  - setValues
```
public void setValues(java.lang.String... values)
```
    Set the values of a SelectItem with multiple=true.
    
    Parameters:
    
    values - the SelectItem values
  - isMultiple
```
public java.lang.Boolean isMultiple()
```
    If true, multiple values may be selected.
    The SelectItem will either render as a drop-down allowing multiple selections, or a multi-row list of options similar to a small headerless ListGrid, based on the MultipleAppearance setting.
    The logical value of the formItem, as retrieved by getValue() and set via setValue(), is an Array of Strings reflecting the selected values.
    When this value is true, we disable doubleClick events by default, instead issuing two single clicks by forcibly setting noDoubleClicks: true. If you need to work with doubleClick events, you can disable this default behavior by explicitly setting formItem.pickListProperties.noDoubleClicks: false.
    Note: multiple:true SelectItems do not currently support optionDataSource binding. You can get around this by calling DataSource.fetchData directly and calling dsResponse.data.getValueMap() to obtain a valueMap.
    
    Returns:
    
    Boolean

  - 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
  - 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.
    The criteria returned by this method are used to decide which options should appear in the drop-down PickList shown by this SelectItem.
    Static criteria, specified via pickListCriteria, will always be included in addition to criteria returned by this method.
  - 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 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.
    
    Returns:
    
    value of this element
  - 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
  - fetchData
```
