title: Dynamic select menu / cascading drop down in Rails?
body: <p>Could someone suggest a guide/tutorial for implementing a dynamic select menu / cascading drop down in Rails using best practices? Or possibly recent Stackoverflow questions around the same topic. Possibly I'm searching the wrong terms.</p>
  
  <p>I've taken a look at this railscast: <a href="http://railscasts.com/episodes/88-dynamic-select-menus-revised?view=asciicast" rel="nofollow">#88 Dynamic Select Menus (revised)</a> but am not convinced using a csv file to store the options is the best way to go about this.</p>
  
  <p>Everything else that I've found regarding dropdowns seems incomplete or outdated.</p>
