Anybody used Greensock drag and can it be dropped on a target symbol?

Anybody used Greensock's JS Draggable ( http://www.greensock.com/draggable ) and can it be dropped on a target symbol?

ie Can I have a draggable circle and if dragged onto a target square the animation will go to another frame, otherwise it returns to it's original position?

I can't seem to find if it can do that or not.

The reason I want to use Greensock is so the draggable item works correctly on a Responsive Scaling animation.

Thanks in advance.
