ContextMenu

A context menu widget.

Included in: dx.webappjs.js, dx.all.js

The dxContextMenu widget displays a single-level or multi-level context menu that performs an action when an item is clicked.

You can create a widget using one of the following approaches.

  • jQuery
    Use the dxContextMenu jQuery plug-in.

    HTML
    <div id="targetElement"></div>
    <div id="contextMenu"></div>
    JavaScript
    var menuItems = [
        { text: "Hide" },
        { text: "Delete" },
        {
            text: "Clipboard",
            items: [
                { text: "Copy text" },
                { text: "Clear text" },
                { text: "Paste text" }
            ]
        }
    ];
    $("#contextMenu").dxContextMenu({
        items: menuItems,
        target: '#targetElement'
    });
  • Knockout
    Add a div element and apply the dxContextMenu binding to this element.

    HTML
    <div id="targetElement"></div>
    <div data-bind="dxContextMenu: {
        items: menuItems,
        target: '#targetElement'
    }"></div>
  • Angular
    Add a div element and apply the dx-context-menu directive to this element.

    HTML
    <div id="targetElement"></div>
    <div dx-context-menu="{
        items: menuItems,
        target: '#targetElement'
    }"></div>

Note that DevExtreme widgets require you to link the jQuery and Globalize libraries to your application. If you use the Knockout or Angular approach, the Knockout or Angular library is also required.
