title: Custom rendering of Zend_Navigation
body: <p>I am using a navigation XML file in conjunction with my Zend Framework MVC app.</p>
  
  <p>A top level menu is rendered at the top of my layout. The code to produce it looks like this:</p>
  
  <pre><code>$this-&gt;navigation()-&gt;menu()-&gt;renderMenu(null,array('maxDepth'   =&gt;  0));
  </code></pre>
  
  <p>This will automatically render an unordered list of links that I have styled into my top menu.
  Now, I want to render the submenu (to render the active container tree) taking advantage of all the built-in Zend_Navigation goodness (MVC and ACL integration) but with custom markup. I would do this by inserting this:</p>
  
  <pre><code>$this-&gt;navigation()-&gt;menu()-&gt;renderSubMenu();
  </code></pre>
  
  <p>In fact, I have a very specific set of markup that I need to render this with. It is so drastically different I do not think I could style an unordered list to accomodate my desired presentation.</p>
  
  <p>Is there a simple way (or complicated if need be ;) to customize a submenu? </p>
