activeStateEnabled

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

Type:

Boolean

Default Value: true

This property is used when the UI component is displayed on a platform whose guidelines include the active state change for UI components.

Function

Function parameters:
event:

Event (jQuery or EventObject)

    $("#contextMenuContainer").dxContextMenu({
        // ...
        closeOnOutsideClick: function(e) {

    );
}

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

dataSource

Binds the UI component to data.

The ContextMenu works with collections of string values or objects.

Depending on your data source, bind the ContextMenu 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";
        $("#contextMenuContainer").dxContextMenu({
            // ...

  • Any other data source
    Implement a CustomStore.

Regardless of the data source on the input, the ContextMenu 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

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 ].

  • The stores and DataSource have 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 property as shown in the articles about changing properties in jQuery, Angular, React, and Vue.

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.

Raised Events: onOptionChanged

The items array can contain:

  • 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:

JavaScript
contextMenuInstance.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.
