[jQuery] How to fit the draggable inside the droppable?


Hi,
How can I fit the draggable inside the droppable? I know I can use
"fit" but that is just too hard to fit in the droppable. Also, if the
droppable already consists an element then I want to kill the
draggable but not destroy or disable it.
