title: How to add a div to KnpMenu (Symfony2.1)
body: <p>I would like to make a drowdown box whenever someone hovers over a menu button, im generating the menu with the KnpMenuBundle.</p>
  
  <p>What i would like to get is a structure like this:</p>
  
  <pre><code>&lt;lu&gt;
      &lt;li&gt;&lt;a&gt;...&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;
          &lt;a&gt;...&lt;/a&gt;
          &lt;div&gt;...&lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;&lt;a&gt;...&lt;/a&gt;&lt;/li&gt;
  &lt;lu&gt;
  </code></pre>
  
  <p>If possible i would like to render a controller from inside the div. </p>
  
  <p>Can this be done?</p>
  
  <p>If i missed something in the documentation please post a link because i have been searching for hours...</p>
