title: Add a unique ID to Drupal Views list groupings
body: <p>I'm using Views 3 in Drupal 7 to output a list of fields and using a grouping field to generate separate lists. I need each of the groupings to have a unique ID attribute applied to the &lt; ul > but they don't by default.</p>
  
  <p>As far as I'm aware I would need to edit the <a href="http://api.drupal.org/api/views/theme!views-view-list.tpl.php/7" rel="nofollow">views-view-list.tpl.php</a> template but I don't know how to achieve a unique ID per iteration.</p>
  
  <p>Can anyone help please?</p>
