contextmenu

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The contextmenu global attribute is the id of a <menu> to use as the contextual menu for this element.

A context menu is a menu that appears upon user interaction, such as a right-click. HTML now allows us to customize this menu. Here are some implementation examples, including nested menus.

Example

HTML

html

<body contextmenu="share">
  <menu type="context" id="share">
    <menu label="share">
      <menuitem label="Twitter" onclick="shareViaTwitter()"></menuitem>
      <menuitem label="Facebook" onclick="shareViaFacebook()"></menuitem>
    </menu>
  </menu>
  <ol>
    <li>
      Anywhere in the example you can share the page on Twitter and Facebook
      using the Share menu from your context menu.
    </li>
    <li contextmenu="changeFont" id="fontSizing">
      On this specific list element, you can change the size of the text by
      using the "Increase/Decrease font" actions from your context menu
    </li>
    <menu type="context" id="changeFont">
      <menuitem label="Increase Font" onclick="incFont()"></menuitem>
      <menuitem label="Decrease Font" onclick="decFont()"></menuitem>
    </menu>
    <li contextmenu="ChangeImage" id="changeImage">
      On the image below, you can fire the "Change Image" action in your Context
      Menu.<br />
      <img
        src="promobutton_mdn5.png"
        contextmenu="ChangeImage"
        id="promoButton"
        alt="Better CSS Docs for a better web" />
      <menu type="context" id="ChangeImage">
