A context menu is a type of menu in a graphical user interface (GUI) that appears when you perform right click operation. For this operation, you have to disable the openOnClick property. In this Menu control you can use a context menu by specifying the type of menu as ContextMenu using menuType. A context also provides support for nested level of menu items.

Before you use the context menu, provide the target area for it and mention that area id in the property named as contextMenuTarget.

In the following example, a context menu for the division containing text is created. In this, when you perform right click operation, the following menu appears with open, edit, etc.

Add the following code in your HTML page.

HTML

<div>
        <div id="target" class="textarea">
            HTML is written in the form of HTML elements consisting of tags enclosed in angle
            brackets (like
            &lt;html&gt;
            ),within the web page content. HTML tags most commonly come in pairs like and ,although
            some tags, known as empty elements, are unpaired, for example
            &lt;img&gt;. The purpose of a web browser is to read HTML documents and compose them into
            visible or audible web pages. The browser does not display the HTML tags, but uses
            the tags to interpret the content of the page.
