public class MultiPickerItem extends StaticTextItem
MultiPickerItem provides an interface to edit data involving whether a record has membership in a certain set, for example, where specific Employees are part of specific Teams.

MultiPickerItem is a compact editor for this purpose, using a `pop-up` to present a `Shuttle`-style interface for moving records or values being different categories. When the MultiPickerItem pop-up is not active, MultiPickerItem just displays the currently chosen values as read-only text, which can be `clipped` to appear in a very small space.

Note: if your use case is a search interface to generate criteria, in either the FilterEditor of a ListGrid/TreeGrid, or in a SearchForm, SetFilterItem is the right choice. Generally, use SetFilterItem for searching, and MultiPickerItem (or `Shuttle`) for editing.

To configure a MultiPickerItem, provide either an optionDataSource or a valueMap. The `value` stored by a MultiPickerItem is the set of selected items, as either a list of `primary key values` if an optionDataSource is used, or as just ID values if an valueMap is used.

The item's picker-component can be customized via settings such as `sortField`, or by configuring `auto-children` like the `search-form`, the `main pickList-grid` or the separate list of `selected values`. You can use `optionFilterContext` to apply custom `requestProperties` to fetches from the main `pickList` grid.

    Parameters:
      `canExpand` - New canExpand value. Default value is true
    Returns:
      `MultiPickerItem` instance, for chaining setter calls

  - ### getCanExpand

    public Boolean getCanExpand()
    Should we show an `expansionIcon` expand button allowing the user to show an expanded view of the `pickList` with multiple fields.

    `canExpand` only applies to MultiPickerItems with selectionStyle set to "pickList" or "pickTree" and an explicitly specified set of `expandedPickListFields` to display within the expanded view.

  - ### setDeriveUniqueValues

    public MultiPickerItem setDeriveUniqueValues(Boolean deriveUniqueValues)
    If this MultiPickerItem is deriving its options from a dataSource, should it ensure unique field values by `grouping by` the value field for this item? This is not necessary if the target dataSource value field is already unique - for example if this is the primaryKey field for a dataSource.

    Note that for MultiPickerItems with `deriveUniqueValues:true`, any `expandedPickListFields` to be displayed in the `expanded view` will not be able to display meaningful values unless a `summaryFunction` is supplied to produce aggregated values from the grouped data. This may be achieved by specifying summaryFunctions directly on the `optionFilterContext`, or on the `operationBinding` for the `fetch operation`.

    Note : This is an advanced setting

    Parameters:
      `deriveUniqueValues` - New deriveUniqueValues value. Default value is false
    Returns:
      `MultiPickerItem` instance, for chaining setter calls

  - ### getDeriveUniqueValues

    public Boolean getDeriveUniqueValues()
    If this MultiPickerItem is deriving its options from a dataSource, should it ensure unique field values by `grouping by` the value field for this item? This is not necessary if the target dataSource value field is already unique - for example if this is the primaryKey field for a dataSource.

    Note that for MultiPickerItems with `deriveUniqueValues:true`, any `expandedPickListFields` to be displayed in the `expanded view` will not be able to display meaningful values unless a `summaryFunction` is supplied to produce aggregated values from the grouped data. This may be achieved by specifying summaryFunctions directly on the `optionFilterContext`, or on the `operationBinding` for the `fetch operation`.

  - ### setDisplayField

    public MultiPickerItem setDisplayField(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:
      `setDisplayField` in class `FormItem`
    Parameters:
      `displayField` - New displayField value. Default value is null
    Returns:
      `MultiPickerItem` instance, for chaining setter calls

      - `FormItem.getDisplayFieldName()`
      - `FormItem.invalidateDisplayValueCache()`
      - `DataBinding`

    public String getExpandIconSrc()
    `SCImgURL` for the `expansionIcon` while not in expanded mode
    Returns:
      Current expandIconSrc value. Default value is "[SKINIMG]/actions/expand_right.png"

  - ### getFilterForm

    public DynamicForm getFilterForm()
    Dynamic form showing a single text item for filtering the PickList while `SelectionStyle` is "pickList".

    May be hidden by setting `showFilterForm` to false.

    If `canExpand` is true, the filter form will not be displayed in the expanded view, as it would be unclear to the user which of the expanded fields would be filtered by it.

    Instead if `showFilterForm` is true, the pickList will show the `filterEditor` by default, allowing the user to filter by `field`

    Instead of the filterForm, developers may display the standard filterEditor for the pickList in non-expanded view via `pickList autoChild properties`. If you do this the filterForm will not be displayed even if`showFilterForm` is true.

  - ### setIncludeSelectedParents

    public MultiPickerItem setIncludeSelectedParents(Boolean includeSelectedParents)
    For multiPickerItems with `selectionStyle:"pickTree"`, and `canSelectFolders:true`, should selected parent nodes be included in the item's value?

    When `cascading selection` is enabled for a tree, the selected state of parent nodes always reflects the selected state of their children, and it may not be necessary or desirable to explicitly record the parents' selected state in the item's value.

    Some specific use cases where this is the case might include:

    - Creating filter criteria for a target TreeGrid where `TreeGrid.keepParentsOnFilter` is true. In this case filter criteria would not need to include selected parent nodes for the children to be visible in the target tree.
    - Trees where leaves are of a different logical type than their parents. If a tree structure is being used to categorize data, `cascading selection` may be useful to allow the user to easily select all items within a category but application code may not want to include the categories as part of a MultiPickerItem's value

    This property only applies when `cascadeSelection` is true. If cascadeSelection is false, all selected nodes will be present in the items value regardless of their parent/child relationships.

    Parameters:
      `includeSelectedParents` - New includeSelectedParents value. Default value is false
    Returns:
      `MultiPickerItem` instance, for chaining setter calls

  - ### getIncludeSelectedParents

    public Boolean getIncludeSelectedParents()
    For multiPickerItems with `selectionStyle:"pickTree"`, and `canSelectFolders:true`, should selected parent nodes be included in the item's value?

    When `cascading selection` is enabled for a tree, the selected state of parent nodes always reflects the selected state of their children, and it may not be necessary or desirable to explicitly record the parents' selected state in the item's value.

    - Creating filter criteria for a target TreeGrid where `TreeGrid.keepParentsOnFilter` is true. In this case filter criteria would not need to include selected parent nodes for the children to be visible in the target tree.
    - Trees where leaves are of a different logical type than their parents. If a tree structure is being used to categorize data, `cascading selection` may be useful to allow the user to easily select all items within a category but application code may not want to include the categories as part of a MultiPickerItem's value

  - ### setOptionDataSource

    public MultiPickerItem setOptionDataSource(DataSource optionDataSource)
    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 `FormItem.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 `FormItem.displayField` is specified for a FormItem and `optionDataSource` is unset, `optionDataSource` will default to the form's current DataSource

  - ### setDefaultProperties

    public static void setDefaultProperties(MultiPickerItem multiPickerItemProperties)
    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:
      `multiPickerItemProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`
