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. HTML5 now allows us to customize this menu. Here are some implementation examples, including nested menus.

Example

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="https://developer.mozilla.org/media/img/promote/promobutton_mdn5.png"
          contextmenu="ChangeImage" id="promoButton" />
      <menu type="context" id="ChangeImage">
        <menuitem label="Change Image" onclick="changeImage()"></menuitem>
      </menu>
    </li>
  </ol>
</body>

JavaScript

function shareViaTwitter() {
  window.open("https://twitter.com/intent/tweet?text=" +
      "Hurray! I am learning ContextMenu from MDN via Mozilla");
}

function shareViaFacebook() {
  window.open("https://facebook.com/sharer/sharer.php?u=" +
      "https://developer.mozilla.org/en/HTML/Element/Using_HTML_context_menus");
}

function incFont() {
  document.getElementById("fontSizing").style.fontSize = "larger";
}

function decFont() {
  document.getElementById("fontSizing").style.fontSize = "smaller";
}

function changeImage() {
  var index = Math.ceil(Math.random() * 39 + 1);
  document.images[0].src =
      "https://developer.mozilla.org/media/img/promote/promobutton_mdn" +
      index + ".png";
}

[1] An experimental implementation is available via the command line option --enable-blink-features=ContextMenu. Until Chrome 52 and Opera 39 it was additionally available by enabling the Experimental Web Platform features option, but got removed from that due to a Web compatibility issue. Support for this feature is requested in Chromium bug 87553.
