title: How do I style a submenu of a ContextMenu in wpf
body: <p>I can style the contextmenu (.style) containing the items and I can style the menu items fine (.ItemTemplate). But how do I style the submenu that pops out when a menuitem has menuitems? </p>
  
  <p>Like:</p>
  
  <pre><code>&lt;ContextMenu&gt;
      &lt;MenuItem Header="Font Style"&gt;          
                  &lt;MenuItem Header="Under Line" IsCheckable="true"/&gt;
                  &lt;MenuItem Header="Italic" IsCheckable="true"/&gt;
                  &lt;MenuItem Header="Bold" IsCheckable="true"/&gt;
      &lt;/MenuItem&gt;
  &lt;/ContextMenu&gt;
  </code></pre>
