accessKey
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.
animation
closeOnOutsideClick
Event (jQuery or EventObject)
The event that caused widget closing. It is a dxEvent or a jQuery.Event when you use jQuery.
The function passed to this option enables you to specify a custom condition for closing the widget. For instance, you can prevent closing until a user clicks a certain element.
jQuery
$(function () { $("#contextMenuContainer").dxContextMenu({ // ... closeOnOutsideClick: function(e) { return e.target === $("#someElement").get()[0]; } }); });
Angular
import { DxContextMenuModule } from "devextreme-angular"; // ... export class AppComponent { // ... closeOnOutsideClick (e) { return e.target === document.getElementById("someElement"); } } @NgModule({ imports: [ // ... DxContextMenuModule ], // ... })
<dx-context-menu ... [closeOnOutsideClick]="closeOnOutsideClick"> </dx-context-menu>
dataSource
If you use DevExtreme ASP.NET MVC Controls, refer to the Bind Controls to Data article.
The ContextMenu works with collections of string
values or objects.
Depending on your data source, bind the ContextMenu to data as follows. If the data source provides objects, also specify the itemTemplate. You can skip this part if the objects contain fields described in the Default Item Template section.
Data Array
Assign the array to the dataSource option.Read-Only Data in JSON Format
Set the dataSource option to the URL of a JSON file or service that returns JSON data.OData
Implement an ODataStore.Web API, PHP, MongoDB
Use one of the following extensions to enable the server to process data according to the protocol DevExtreme widgets use:Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.
jQuery
JavaScript$(function() { let serviceUrl = "https://url/to/my/service"; $("#contextMenuContainer").dxContextMenu({ // ... 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 ContextMenu always wraps it in the DataSource object. This object allows you to sort, filter, group, and otherwise shape data. To get its instance, call the getDataSource() method.
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.
disabledExpr
Specifies the name of the data source item field whose value defines whether or not the corresponding widget item is disabled.
elementAttr
Specifies the attributes to be attached to the widget's root element.
jQuery
$(function(){ $("#contextMenuContainer").dxContextMenu({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-context-menu ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-context-menu>

height
This option accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"80%"
,"inherit"
.Function
A function returning either of the above. For example:JavaScriptheight: function() { return window.innerHeight / 1.5; }
itemComponent
An alias for the itemTemplate option specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.
itemRender
An alias for the itemTemplate option specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.
items
If you need to update the widget items, reassign the entire items[] array as shown in the following example:
contextMenuInstance.option('items', newItems);
As an alternative to items, you can use the dataSource option. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
Particular fields in objects can control the widget's appearance. See Default Templates for more information.
