React Menu Props

An object defining configuration options for the Menu widget.

See Also

accessKey

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.

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

Binds the widget to data.

Default Value: null

If you use DevExtreme ASP.NET MVC Controls, refer to the Bind Controls to Data article.

The Menu works with collections of string values or objects.

Depending on your data source, bind the Menu to data as follows. If the data source provides objects, also specify the itemTemplate. You can skip this part if the objects contain fields described in the items section.

  • Data Array
    Assign the array to the dataSource option.

  • Read-Only Data in JSON Format
    Set the dataSource option to the URL of a JSON file or service that returns JSON data.

  • OData
    Implement an ODataStore.

  • Web API, PHP, MongoDB
    Use one of the following extensions to enable the server to process data according to the protocol DevExtreme widgets use:

    Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.

  • Any other data source
    Implement a CustomStore.

Regardless of the data source on the input, the Menu always wraps it in the DataSource object. This object allows you to sort, filter, group, and perform other data shaping operations. To get its instance, call the getDataSource() method.

NOTE

Please review the following notes about data binding:

  • Do not specify the items option if you specified the dataSource, and vice versa.

  • Data field names should not contain the following characters: ., ,, :, [, and ].

  • DataSource and stores provide methods to process and update data. However, the methods do not allow you to perform particular tasks (for example, replace the entire dataset, reconfigure data access at runtime). For such tasks, create a new array, store, or DataSource and assign it to the dataSource option as shown in the articles about changing options in jQuery, Angular, React, and Vue.

If you need to update the widget items, reassign the entire items array as shown in the following example:

JavaScript
menuInstance.option('items', newItems);
