jQuery - Best way to populate a hidden field with list data?
<p>I have two unordered lists populated with users. The idea is to drag users from one list to add them to a group in the other list. Each user also has a dropdown to select a role in the group.</p>

<p>I'd like to add to/remove from a hidden field with the values of the "added" users and their role. I'm not really sure though how to do that.</p>

<p>I have a jsfiddle showing the general idea here: <a href="http://jsfiddle.net/KPdAX/" rel="nofollow">http://jsfiddle.net/KPdAX/</a></p>
