Drag and Drop free form

If I understand well, you want the drag item go back to its original position if is dropped onto the incorrect drop zone. What I have changed initially:
1. Unchecked "Reveal drag items one at a time"
2. Set states of all drag items to hidden (all except first drag item)
3. Set state of the next drag item to normal when the previous drag item is dropped to correct drop zone
4. Created a very short (00.10) and very fast motion path for the drag item and trigger to move this drag item along the path if is dropped to incorrect drop zone (path should go from the middle of the incorrect drop zone to the drag item original position) 

Basically, the next drag item is revealed only if the previous drag item is dropped onto the correct drop zone. Otherwise, it will move back to its original position ready to be dragged again. Let me know if this helps.
