title: Using helper: 'original' with sortable() and draggable() doesn't appear to work
body: <p>I have a simple HTML page on which I want to be able to drag the divs numbered 6-10 into the sortable list, which already contains divs numbered 1-5. When I set the draggable helper value to 'clone', this page works perfectly well. However, I want to use the 'original' helper. This doesn't appear to work at all. </p>
  
  <p>Can anyone suggest an alternative? I've tried making "dropTarget" a droppable() area, but that doesn't seem to work. I imagine they are conflicting with each other or something. Any advice would be very welcome!</p>
