title: How do I implement multi-select autocomplete text box in Rails?
body: <p>If you go <a href="http://streeteasy.com/" rel="nofollow">here</a>, and click in the search box for the field 'Where' and choose any of the options, you will see that they get added to the field and you can continue adding terms to the 'where' field.</p>
  
  <p>I implemented search functionality in it's own model, similar to what Ryan Bates covered in <a href="http://railscasts.com/episodes/111-advanced-search-form-revised?view=asciicast" rel="nofollow">this Railscast</a>.</p>
  
  <p>I am not quite sure how to get the search suggestion &amp; multi-select functionality working. Any ideas or links to either any tutorials or Railscasts or just a general suggestion about how I might implement this?</p>
  
  <p>Thanks.</p>
  
  <p>P.S. I can view the <a href="http://railscasts.com/episodes/399-autocomplete-search-terms" rel="nofollow">autocomplete Railscast</a> but that doesn't cover the multi-select aspect.</p>
