title: JQuery draggable - allow containment to multiple containers?
body: <p>I'd like to allow users to drag an element from one container to another while still being constrained from being able to drag the element outside of either of those two containers.  I have everything working perfectly except the part where they can drag to another container.</p>

  <p>I thought <a href="https://stackoverflow.com/questions/5564317/set-more-than-one-containment-in-jquery-draggable">this post</a> seemed like the answer but it doesn't appear to work for me.</p>
