title: Ruby on Rails Search filed drop-down that filers items from table
body: <p>I am trying to create a dropdown that allows selection ONLY from items in a table column. Since there are thousands of items my simple dropdown is not practical, so I was hoping to create a search field where the user can begin typing out the name of the item and it alters the dropdown so they can select an item from the able ONLY. I know this is hard to picture but something similar to this: <a href="http://www.gsmarena.com/compare.php3" rel="nofollow">http://www.gsmarena.com/compare.php3</a></p>
  
  <p>I am quite new to Ruby and have searched quite a bit to find a solution, but I do not know exactly what to search for to complete this task. I am hoping that you can point me in the right direction. Thanks. </p>
