title: Jquery + Rails - Drag & drop between two lists
body: <p>Background: I am upgrading an old Rails 2 application to Rails 3. This application has a feature where users can drag &amp; drop elements between two lists. I tried to duplicate the functionality by using, Jquery demo:</p>

  <p>I am able to show two lists and drag &amp; drop between them. But I am not well versed with Jquery and don't know how to save data.</p>
  
  <p>Any help or pointers would be appreciated.</p>
