title: How to use Selectize theme in ui-select?
body: <p>i have problem to apply selectize theme to my ui-select in angular.js App. I followed the instruction here - <a href="https://github.com/angular-ui/ui-select" rel="nofollow">https://github.com/angular-ui/ui-select</a> . It seems easy enough but i can't get the input to show up,</p>
  
  <p>DEMO - <a href="http://plnkr.co/edit/TFKeMTCNVuginJ31IH80?p=preview" rel="nofollow">http://plnkr.co/edit/TFKeMTCNVuginJ31IH80?p=preview</a> </p>
  
  <pre><code>&lt;ui-select multiple ng-model="multipleDemo.colors" theme="selectize" ng-disabled="disabled" style="width: 300px;"&gt;
  &lt;ui-select-match placeholder="Select colors..."&gt;{{$item}}&lt;/ui-select-match&gt; &lt;!-- WHERE IS THE INPUT? --&gt;
  &lt;ui-select-choices repeat="color in availableColors | filter:$select.search"&gt;
    {{color}}
  &lt;/ui-select-choices&gt;
  </code></pre>
  
  <p></p>
  
  <p>that's the demo that i forked from ui-select's. As you can see, the input doesn't show up. 
  What I miss here ?</p>
