aps/MultiSelect

A list from which a user may select one or several items.

The ``aps/MultiSelect`` widget allows you to display a list from which a user may select one or several items. To make selection, the user can use special buttons or Drag and Drop.

Compatibility

All user panels - CP and UX1

Overview

The aps/MultiSelect widget builds and presents a list of entries from a data source reference from the store property. A store is an object based on the aps/Store or aps/Memory module. Every entry consists of two properties:

  • data

    Data that will be visually displayed in the list item.

  • value

    Item value that will be saved if the user selects this item.

The items selected by the user are stored in the values object of the dojox/mvc/StatefulArray type that contains values of the items selected by the user. It is available for dynamic programmatic change.

If you need to create an aps/MultiSelect container with already selected items, you should pass to the constructor a StatefulArray object with already defined item values. If the property is not defined when the widget is being created, a new empty object will be created.

If you programmatically place into the object a value that does not match the value property of any item, a new item will be created.

Example

RUN DEMO

require(["aps/load", "aps/Memory", "dojox/mvc/StatefulArray", "aps/ready!"],
  function(load, Memory, StatefulArray){
    "use strict";

    var data = [{ label: "SiteBuilder", value: 1 },
           { label: "2 Additional Gigabytes", value: 2 },
           { label: "5 Additional Gigabytes", value: 3 }];

    var store = new Memory({
      idProperty: "value",
      data:       data
    });

    var valuesArray = new StatefulArray([1]);

    load(["aps/PageContainer", [
      ["aps/Panel", { title: "Load example" }, [
         ["aps/MultiSelect", {
          titleLeft:     "Available:",
          store:         store,
          titleRight:    "Selected:",
          values:        valuesArray,
          labelAttr:    "label"
         }]
    ]]]]);
});

Public Properties

PROPERTY

TYPE

DEFAULT

DESCRIPTION

disabled

boolean

Should this widget respond to user input Default value: false.

gridSize

string

undefined

This specifies the widget width that is relevant only for widgets inside Container, FieldSet, or Tiles.

isBusy

boolean

false

If the widget is busy then this property is true.

label

string

“”

Text that is shown as a label if the widget is placed inside a aps/FieldSet.

labelAttr

string

label

The entries in the drop down list come from this attribute in the dojo.

source

object

Data available for selection.

titleLeft

string

Left list title.

titleRight

string

Right list title.

values

array

Data selected by the user.

visible

boolean

true

If this property value is set to true, then the widget is visible.

gridSize string

This specifies the widget width that is relevant only for widgets inside Container, FieldSet, or Tiles. In other cases it will be ignored.

gridSize string contains few options with number values (from 1 to 12) separated by spaces, which specify the grid size of the widget in different layouts:

- md - desktop

- xs - phone

For example, gridSize: “md-4 xs-2”.

All values below 1, e.g. “md-0”, will be replaced with the empty string (“”), values above 12, e.g. “md-14”, will be reduced to 12 (“md-12”).

Default value: undefined.

isBusy boolean

If the widget is busy then this property is true.

Default value: false.

label string

Text that is shown as a label if the widget is placed inside a aps/FieldSet.

Default value: “”.

labelAttr string

The entries in the drop down list come from this attribute in the dojo.store items. If store is set, labelAttr must be set too, unless store is an old-style dojo.data store rather than a new dojo/store. Default value: “label”

source object

Data available for selection. Default value: null

titleLeft string

Left list title. Default value: “”

titleRight string

Right list title. Default value: “”

values array

visible boolean

Default value: true.

Public Methods

METHOD

RETURN

DESCRIPTION

cancel ()

object

Sets the isBusy property to false

destroy ()

undefined

Destroys this widget

get ()

any

Get a property of the Stateful instance

getParents ()

array

Discover and return all parents of the widget

placeAt ()

dijit/_widgetbase
function

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions

set ()

object
function

Set a property of the Stateful instance

startup ()

undefined

Gets started after the DOM fragment is added to the document

cancel

Sets the isBusy property to false.

Return: object

destroy

Destroys this widget. Will also destroy any resources (including widgets) registered via this.own(). This method will also destroy internal widgets such as those created from a template.

Return: undefined

get

Get a property of the Stateful instance. Get a named property of the Stateful object. The property may potentially be retrieved via a getter method in subclasses.

In the base class, this just retrieves the object’s property.

Return: any

getParents

Discover and return all parents of the widget.

Return: array

placeAt

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions. A convenience function providing a simple shorthand mechanism to put an existing (or newly created) widget somewhere in the DOM, and allow chaining.

Return: dijit/_widgetbase function

set

Set a property of the Stateful instance. Sets named properties of the stateful object and notifies the watchers of the property. A programmatic setter may be defined in subclasses.

Return: object function

startup

Gets started after the DOM fragment is added to the document Called after the widget and its children have been created and added to the page, and all related widgets have finished their create() cycle, up through postCreate().

Note that startup() may be called while the widget is still hidden, for example if the widget is inside a hidden dijit/Dialog or an unselected tab of a dijit/layout/TabContainer. For widgets that need to do layout, it’s best to put that layout code inside resize(), and then extend dijit/layout/_LayoutWidget so that resize() is called when the widget is visible.

Return: undefined

Public Events

EVENT

DESCRIPTION

onClick ()

undefined
