how to push Items when using resizable and draggable.


Ok,
I have several items that can be resized to the east and can be
dragged. But when you resize them the other boxes get moved over and
the first (resized) box is under the rest. This is also the same for
when you move them, they get stacked on top of each other. Is there a
way to make them move out of the way?
