Change drag and drop target and item to hidden upon drop?

You can stack the drop targets on top of each other, but instead of setting them to a "Hidden" state, it's better to move them off the slide or mask them when they disappear after the correct drag item is dropped onto the correct target. In the attached example, I used motion paths to move the drop targets across the slide when the correct drag item is placed on the correct drop target. I also used line motion paths to ensure that drag items return to their starting point when dropped on an incorrect drop zone. Attached is a short video demonstrating how this interaction works.
