public class MultiComboBoxItem extends CanvasItem
A MultiComboBoxItem is a combo box that allows the user to select multiple options. Each selected option is represented as a button that can be clicked to deselect the option. The relative layout of the buttons to the combo box is specified with the `layoutStyle` attribute. The buttons will be kept in the order that they were added, with the most recently added button being adjacent to the combo box. `MultiComboBoxItem` uses the `com.smartgwt.client.types.AutoChild` pattern to construct the `comboBox` and the `buttons` so that they can be easily customized. For example, you can customize the criteria used to fetch by using `ComboBoxItem.setPickListFilterCriteriaFunction()` with `setComboBoxProperties()`.

  - ### changePickerIconDefaults

    public static void changePickerIconDefaults(FormItemIcon defaults)

  - ### setAddUnknownValues

    public MultiComboBoxItem setAddUnknownValues(Boolean addUnknownValues)
    Similar to `ComboBoxItem.addUnknownValues`, controls whether additional values can be added to the ComboBox or whether the user must choose from the available values in the picklist only.

    If this setting is changed after the MultiComboBoxItem has been created, the current value of the item is reset to null and all buttons for non-default values (values not in the `FormItem.defaultValue` array) are removed.

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

  - ### getAddUnknownValues

    public Boolean getAddUnknownValues()
    Similar to `ComboBoxItem.addUnknownValues`, controls whether additional values can be added to the ComboBox or whether the user must choose from the available values in the picklist only.

    If this setting is changed after the MultiComboBoxItem has been created, the current value of the item is reset to null and all buttons for non-default values (values not in the `FormItem.defaultValue` array) are removed.

    Returns:
      Current addUnknownValues value. Default value is false

  - ### setAlwaysExitOnTab

    public MultiComboBoxItem setAlwaysExitOnTab(Boolean alwaysExitOnTab)
    If true, hitting tab always exits the field, and will also add a value to the list of selected values if there is match (and depending on the setting for `addUnknownValues`).

    If false, if the user has typed in a value and hits tab, focus remains in the field. If there is a match or if `addUnknownValues` is true, a value will be added. Otherwise, the input cursor remains at the end of the entered value.

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

  - ### getAlwaysExitOnTab

    public Boolean getAlwaysExitOnTab()
    If true, hitting tab always exits the field, and will also add a value to the list of selected values if there is match (and depending on the setting for `addUnknownValues`).

    If false, if the user has typed in a value and hits tab, focus remains in the field. If there is a match or if `addUnknownValues` is true, a value will be added. Otherwise, the input cursor remains at the end of the entered value.

    Returns:
      Current alwaysExitOnTab value. Default value is true

  - ### setAutoExpandComboBox

    public MultiComboBoxItem setAutoExpandComboBox(Boolean autoExpandComboBox)
    When true and `layoutStyle` is "flow" or "flowReverse", the combo box expands to fill remaining horizontal space in each row. As the user selects values and chips are added, the combo box shrinks to accommodate them. When chips fill an entire row, the combo box wraps to the next row and expands to fill that row.

    `comboBoxWidth` acts as a minimum width for the combo box when this mode is active.
    If this method is called after the component has been drawn/initialized: Setter for `autoExpandComboBox`.

    Parameters:
      `autoExpandComboBox` - new value. Default value is false
    Returns:
      `MultiComboBoxItem` instance, for chaining setter calls

  - ### getAutoExpandComboBox

    public Boolean getAutoExpandComboBox()
    When true and `layoutStyle` is "flow" or "flowReverse", the combo box expands to fill remaining horizontal space in each row. As the user selects values and chips are added, the combo box shrinks to accommodate them. When chips fill an entire row, the combo box wraps to the next row and expands to fill that row.

  - ### pendingStatusChanged

    public Boolean pendingStatusChanged(DynamicForm form, FormItem item, boolean pendingStatus, Object newValue, Object value)
    Notification method called when `showPending` is enabled and this `MultiComboBoxItem` 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, when displayed in the pending state and a `pendingButtonStyle` is set, then:

    - If `useInsertionOrder` is `false`, buttons for any new values will have their `baseStyle` set to `pendingButtonStyle`; otherwise
    - (`useInsertionOrder` is `true`) buttons for values will have their `baseStyle` set to `pendingButtonStyle` if either the value is new or it is in a different place within the value array.
    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.

  - ### showValue

    public void showValue(Object displayValue, Object dataValue, DynamicForm form, CanvasItem item)
    This method will be called whenever this FormItem's value is being set via a programmatic call to e.g: `DynamicForm.setValues()` or `FormItem.setValue()` and may be overridden by CanvasItems intended to support displaying data values to update the embedded Canvas to reflect the value passed in.

    The value of a MultiComboBoxItem to the form is an array of valueField values corresponding to the selected combo box options.

    Parameters:
      `displayValue` - new display value for the item. This is the value after applying any custom formatter or valueMap
      `dataValue` - underlying data value for the item
      `form` - the dynamicForm in which this item is contained
      `item` - the live form item instance

  - ### setDefaultProperties

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