title: Autocomplete text-field version of dynamic select menu?
body: <p>I would like to combine to logic from the following railscasts:</p>
  
  <p>102 Auto-Complete Association (<a href="https://gist.github.com/2347355" rel="nofollow">https://gist.github.com/2347355</a>)
  AND
  88 Dynamic Select Menus</p>
  
  <p>So as an example, we could say State is selected, and depending on which state is typed a list of cities are populated into the second autocomplete field. Importantly if someone enters a state that doesn't exist it is accepted by the field, and no cities are populated into the city field.</p>
  
  <p>Thanks everyone.</p>
