title: Javascript multiselect and autocomplete plugin
body: <p>I am looking for a js/jquery plugin for select boxes.</p>
  
  <p>Requirements are as following:</p>
  
  <ol>
  <li>Allow multiselection of items, ideally without repetition (remove items which were already chosen)</li>
  <li>Autocompletion, like in <a href="http://jqueryui.com/demos/autocomplete/" rel="nofollow">jquery autocomplete</a> or <a href="http://harvesthq.github.com/chosen/" rel="nofollow">chosen</a></li>
  <li>User should be allowed to enter values, that aren't present in initial selection.</li>
  <li>It should be able to grind large amount of options fast. Amount is about 3 to 10 thousand. </li>
  <li>It should be able to handle unicode characters for autocompletion.</li>
  </ol>
  
  <p>I've used <a href="http://harvesthq.github.com/chosen/" rel="nofollow">chosen</a> before, and it fits on most requirements, except 4 and 5.</p>
  
  <p>Does domething like this exist? Or at least something close and avaiable for forking?</p>
