title: ng-options skip the first element
body: <p>How can i force from ng-options to skip the first element?</p>
  
  <p>i tried: <code>ng-show="!$first"</code> which works on ng-repeat but it's not working on ng-options</p>
  
  <p>this is my code:</p>
  
  <pre><code>&lt;select data-ng-model="minutes_per_slot" data-ng-options="slot as slot + ' minutes' for slot in all_slots"&gt;&lt;/select&gt;
  </code></pre>
  
  <p>Controller:</p>
  
  <pre><code>$scope.all_slots = ["00","5","10","15","20","25"];
  </code></pre>
  
  <p>i want no option contains the 00, but i can't remove it from the array.</p>
  
  <p>any suggestions?</p>
