React Menu Props
An object defining configuration properties for the Menu UI component.
See Also
accessKey
Specifies the shortcut key that sets focus on the UI component.
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
Specifies whether the UI component changes its visual state as a result of user interaction.
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components.
adaptivityEnabled
Specifies whether adaptive rendering is enabled. This property is in effect only if the orientation is "horizontal".
If you enable adaptive rendering, the Menu is shown as a list icon, and Menu items are arranged hierarchically like TreeView items. This functionality is enabled only if the container's width is less than the Menu width.
The following code example sets the container's width to 400 pixels, sets the Menu width to 500 pixels, and enables adaptive rendering to demonstrate the behavior described above.
jQuery
$(function() { $("#menu").dxMenu({ // ... adaptivityEnabled: true, width: 500 }); });
<div id="container"> <div id="menu"></div> </div>
#container { width: 400px; }
Angular
<div id="container"> <dx-menu ... [adaptivityEnabled]="true" [width]="500" > </dx-menu> </div>
#container { width: 400px; }
Vue
<template> <div id="container"> <DxMenu ... :adaptivity-enabled="true" :width="500" /> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxMenu from 'devextreme-vue/menu'; export default { components: { DxMenu }, data() { return { // ... }; } }; </script> <style> #container { width: 400px; } </style>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Menu } from 'devextreme-react/menu'; function App() { return ( <div id="container"> <Menu ... adaptivityEnabled={true} width={500} /> </div> ); } export default App;
#container { width: 400px; }
animation
Set this object to null or undefined to disable animation.
cssClass
Specifies the name of the CSS class to be applied to the root menu level and all submenus.
Use this property to customize the current menu in isolation from other menus created on the same page.
dataSource
Binds the UI component to data.
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 property 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 UI components 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.
jQuery
JavaScript$(function() { let serviceUrl = "https://url/to/my/service"; $("#menuContainer").dxMenu({ // ... dataSource: DevExpress.data.AspNet.createStore({ key: "ID", loadUrl: serviceUrl + "/GetAction", insertUrl: serviceUrl + "/InsertAction", updateUrl: serviceUrl + "/UpdateAction", deleteUrl: serviceUrl + "/DeleteAction" }) }) });

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.
Review the following notes about data binding:
Do not specify the items property if you specified the dataSource, and vice versa.
Data field names cannot be equal to
this
and should not contain the following characters:.
,:
,[
, and]
.
jQuery
- The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Get and Set Properties.
Angular
- The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.
Vue
- The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.
React
- The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Controlled Mode.
disabled
Specifies whether the UI component responds to user interaction.
disabledExpr
Specifies the name of the data source item field whose value defines whether or not the corresponding UI component item is disabled.
displayExpr
Specifies the data field whose values should be displayed.
The current item's data object.
The displayed value.
Set this property to the name of a data field that provides displayed values...
displayExpr: "name"
... or to a function that returns the displayed value:
displayExpr: function(item) { // "item" can be null return item && 'ID: ' + item.id + ', Name: ' + item.name; }
elementAttr
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){ $("#menuContainer").dxMenu({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-menu ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-menu>
import { DxMenuModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxMenuModule ], // ... })
Vue
<template> <DxMenu ... :element-attr="menuAttributes"> </DxMenu> </template> <script> import DxMenu from 'devextreme-vue/menu'; export default { components: { DxMenu }, data() { return { menuAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React from 'react'; import Menu from 'devextreme-react/menu'; class App extends React.Component { menuAttributes = { id: 'elementId', class: 'class-name' } render() { return ( <Menu ... elementAttr={this.menuAttributes}> </Menu> ); } } export default App;
focusStateEnabled
Specifies whether the UI component can be focused using keyboard navigation.
height
Specifies the UI component's height.
This property accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"20vh"
,"80%"
,"inherit"
.Function (deprecated since v21.2)
Refer to the W0017 warning description for information on how you can migrate to viewport units.
hideSubmenuOnMouseLeave
Specifies whether or not the submenu is hidden when the mouse pointer leaves it.
hint
Specifies text for a hint that appears when a user pauses on the UI component.
hoverStateEnabled
Specifies whether the UI component changes its state when a user pauses on it.
itemComponent
An alias for the itemTemplate property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.
itemRender
An alias for the itemTemplate property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.
items[]
Holds an array of menu items.
The items array can contain:
- Objects with fields described in this section
- Objects with any other fields. In this case, specify the itemTemplate.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
menuInstance.option('items', newItems);
As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
