title: How to theme a menu block in Drupal?
body: <p>This should really be a basic question but I simply don't get it after hours of searching. The question is, how do I theme menu blocks in Drupal 7? </p>
  
  <p>I've created three different blocks all based on the main menu. Now I want to:</p>
  
  <ol>
  <li><p>create unique HTML for all three blocks, that means modifing the surrounding  wrapper and the <code>&lt;ul&gt;</code> and <code>&lt;li&gt;</code> that builds the menu. I wanna set special classes and remove all of the Drupal-added stuff</p></li>
  <li><p>attach different classes to the different levels within each block. One of blocks will show two levels of the menu, i.e. it will display a submenu. I want to set a special class on the  for the submenu...</p></li>
  </ol>
  
  <p>This seems impossible... :(</p>
  
  <p>Thank you in advance for the help!!!!</p>
