Revision 1122793 of contextmenu

<div>{{HTMLSidebar("Global_attributes")}}</div>

<p>The <code><strong>contextmenu</strong></code> <a href="/en-US/docs/Web/HTML/Global_attributes">global attribute</a> is the <a href="/en-US/docs/Web/HTML/Global_attributes/id"><strong>id</strong></a> of a {{HTMLElement("menu")}} to use as the contextual menu for this element.</p>

<p>A <em>context menu</em> 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.</p>

<pre class="brush:html; highlight:[1,10,15]">
&lt;body contextmenu="share"&gt;
  &lt;menu type="context" id="share"&gt;
    &lt;menu label="share"&gt;
      &lt;menuitem label="Twitter" onclick="shareViaTwitter()"&gt;&lt;/menuitem&gt;
      &lt;menuitem label="Facebook" onclick="shareViaFacebook()"&gt;&lt;/menuitem&gt;
    &lt;/menu&gt;
  &lt;/menu&gt;
  &lt;ol&gt;
    &lt;li&gt;
      Anywhere in the example you can share the page on Twitter and
      Facebook using the Share menu from your context menu.
    &lt;/li&gt;
    &lt;li contextmenu="changeFont" id="fontSizing"&gt;
      On this specific list element, you can change the size of the text
      by using the "Increase/Decrease font" actions from your context menu
    &lt;/li&gt;
    &lt;menu type="context" id="changeFont"&gt;
      &lt;menuitem label="Increase Font" onclick="incFont()"&gt;&lt;/menuitem&gt;
      &lt;menuitem label="Decrease Font" onclick="decFont()"&gt;&lt;/menuitem&gt;
    &lt;/menu&gt;
    &lt;li contextmenu="ChangeImage" id="changeImage"&gt;
      On the image below, you can fire the "Change Image" action
      in your Context Menu.&lt;br /&gt;
      &lt;img src="https://developer.mozilla.org/media/img/promote/promobutton_mdn5.png"
          contextmenu="ChangeImage" id="promoButton" /&gt;
      &lt;menu type="context" id="ChangeImage"&gt;
        &lt;menuitem label="Change Image" onclick="changeImage()"&gt;&lt;/menuitem&gt;
      &lt;/menu&gt;
    &lt;/li&gt;
  &lt;/ol&gt;

<p>[1] An experimental implementation is available via the command line option <code>--enable-blink-features=ContextMenu</code>. Until Chrome 52 and Opera 39 it was additionally available by enabling the <em>Experimental Web Platform features</em> option, but got removed from that due to a <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=412945">Web compatibility issue</a>. Support for this feature is requested in {{ChromeBug(87553)}}.</p>
