jQuery drag drop elements to multiple lists
<p>I have 2 lists that all contain their own draggable elements. They can be dragged on eachother, but also on the elements in the other lists. Because the accept parameter is set on the droppable it doesn't drop, but it still snaps.</p>

<p>See this example: <a href="http://jsfiddle.net/Zth6x/2/" rel="nofollow">http://jsfiddle.net/Zth6x/2/</a></p>

<p>The green blocks should not be allowed to SNAP to the red blocks, and the other way around.</p>

<p>Because snap is an option from draggable and not from droppable it ignores the accept in droppable.</p>
