title: Select - options and AngularJS - add glyphicon to options
body: <p>I use this select - options in my AngularJS application:</p>
  
  <pre><code>&lt;select data-ng-model="userFilter" data-ng-options="c as c.firstname + ' ' + c.surname for c in vm.users"&gt;
      &lt;option&gt;&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>and now I will add a glyphicon to each option value:</p>
  
  <pre><code>&lt;span class="glyphicon glyphicon-user"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>is there a possibility to do it like this?</p>
