Drag and Drop item not returning to initial state
I am trying to create a drag and drop activity similar to one David Anderson (thanks David) demonstrates here: https://youtu.be/SYJ-duE-r5g?t=407
I'd like to provide the kind of immediate feedback he illustrates where the drop item changes states for correct and incorrect but I am unable to make the drop items return to the initial state once they have been triggered as incorrect. In my case, once an item has been dragged onto the incorrect drop zone, it remains the "incorrect" colour even when dragged off of the incorrect zone. I can't seem to find where to correct this. Can any one point me to resources that might explain how?
