Cp9: Overlapping Drag items
Hi there,
apologies if you already answered a similar question in the forum, but I couldn't find so far a similar discussion.
I've created the following drag and drop activity:

The challenge that I am facing is that I cannot restrict/disable the user from dropping a Drag item (e.g. Lettuce) on a Drop area (e.g. Drop 1) that already has Drag item (e.g. Tomato) on it. As a result, I end up having 2 Drag items on one Drop area.
What I want to happen is: the Drop area to accept only one Drag item irrespective of whether the Drag item is correct or wrong.
Any ideas?
Thank you in advance,
Iasmi
