React Menu Props

An object defining configuration options for the Menu widget.

accessKey

Specifies the shortcut key that sets focus on the widget.

Type:

String

Default Value: null

The value of this option will be passed to the accesskey attribute of the HTML element that underlies the widget.

activeStateEnabled

A Boolean value specifying whether or not the widget changes its state when interacting with a user.

Type:

Boolean

Default Value: true

This option is used when the widget is displayed on a platform whose guidelines include the active state change for widgets.

adaptivityEnabled

Specifies whether adaptive widget rendering is enabled on small screens. Applies only if the orientation is "horizontal".

Type:

Boolean

Default Value: false

On small-screen devices, the Menu is shown as a list icon, and items have a tree structure like the TreeView items if adaptive rendering is enabled.

Watch Video

animation

Configures widget visibility animations. This object contains two fields: show and hide.

Type:

Object

Default Value: { show: { type: 'fade', from: 0, to: 1, duration: 100 }, hide: { type: 'fade', from: 1, to: 0, duration: 100 } }

cssClass

Specifies the name of the CSS class to be applied to the root menu level and all submenus.

Type:

String

Default Value: ''

Use this option to customize the current menu in isolation from other menus created on the same page.

dataSource

A data source used to fetch data to be displayed by the widget.

Default Value: null

This option accepts one of the following.

  • Array of objects
    A simple JavaScript array containing a collection of plain objects.

  • URL
    The URL of a JSON file or service that returns JSON data.

  • DataSource or its configuration object
    A DataSource is an object that provides a handy API for data processing. A DataSource is a stateful object, which means that it saves data processing settings and applies them each time data is loaded. All underlying data access logic of a DataSource is isolated in a Store. A Store provides an API for reading and modifying data. Unlike the DataSource, a Store is a stateless object.

NOTE
Data field names should not contain the following characters: ., ,, :, [, and ]. Their presence may cause issues in the widget's operation.

If the data source is specified using the dataSource option, use the items option only for reading. Updating data items using the items option may cause unexpected results.

To display widget items, a default template can be used. This template is based on the data source fields that are listed in the Default Item Template section of the widget's API.
