Thanks for the reply. Maybe I was too weak with problem explanation.
I meant, can I start drag element, but leave original element in place and drag clone of this element? For example I try drag and drop elements from left panel to right, but I don't want entirely move element to other panel. It is kind of shopping cart behavior. It is important to initiate dragging on one element, but move another. Not sure yet how to switch target draggable element after drag start.
