Vue Menu Props | Vue Documentation

An object defining configuration properties for the Menu UI component.

Specifies the shortcut key that sets focus on the UI component.

Selector: access-key

Default Value: undefined

The value of this property will be passed to the accesskey attribute of the HTML element that underlies the UI component.

Specifies whether the UI component changes its visual state as a result of user interaction.

Selector: active-state-enabled

Default Value: true

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.

Specifies whether adaptive rendering is enabled. This property is in effect only if the orientation is "horizontal".

Selector: adaptivity-enabled

Default Value: false

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.

$(function() {
    $("#menu").dxMenu({
        // ...
        adaptivityEnabled: true,
        width: 500
    });
});

<div id="container">
    <div id="menu"></div>
</div>

#container {
    width: 400px;
}

<div id="container">
    <dx-menu ...
        [adaptivityEnabled]="true"
        [width]="500"
    >
    </dx-menu>
</div>

#container {
    width: 400px;
}

<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>

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;
}

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

Selector: DxAnimation

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

Set this object to null or undefined to disable animation.

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

Selector: css-class

Default Value: ''

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

Binds the UI component to data.

Selector: data-source

Default Value: null

The Menu works with collections of string values or objects.

Depending on your data source, bind 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:

  • DevExtreme.AspNet.Data
  • DevExtreme-PHP-Data
  • devextreme-query-mongodb

  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.

Review the following notes about data binding:

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

• Field names cannot be equal to this and should not contain the following characters: ., :, [, and ].

• Menu does not execute dataSource.sort functions. To implement custom sorting logic, implement columns[].calculateSortValue.

• 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.

• 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.

• 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.

• 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.

Specifies whether the UI component responds to user interaction.

Specifies the name of the data source item field whose value defines whether or not the corresponding UI component item is disabled.

Selector: disabled-expr

Default Value: 'disabled'

Specifies the data field whose values should be displayed.

Selector: display-expr

The current item's data object.

Default Value: 'text'

Set this property to the name of a data field that provides displayed values...

... or to a function that returns the displayed value:

displayExpr: function(item) {
    // "item" can be null
    return item && 'ID: ' + item.id + ', Name: ' + item.name;
}

Specifies the global attributes to be attached to the UI component's container element.

Selector: DxElementAttr

Default Value: {}

$(function(){
    $("#menuContainer").dxMenu({
        // ...
        elementAttr: {
            id: "elementId",
            class: "class-name"

export default App;

Specifies whether the UI component can be focused using keyboard navigation.

Selector: focus-state-enabled

Default Value: true (desktop)

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".

Specifies whether or not the submenu is hidden when the mouse pointer leaves it.

Selector: hide-submenu-on-mouse-leave

Default Value: false

Specifies text for a hint that appears when a user pauses on the UI component.

Selector: hover-state-enabled

Default Value: true

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.

Do not use the items property if you use dataSource, and vice versa.

Specifies which data field contains nested items.

Selector: items-expr

Default Value: 'items'

Specifies a custom template for items.
