<pre class="brush: html">&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;
