One object per drop zone
I've seen lots of discussion on this topic, but no answers - and nothing in the last 6-months. I have a slide with multiple objects that can be moved. The correct answer is the top two red gumdrops should go in either DropL or DropR - one in each. However, even if I put the top 2 red gumdrops in DropL on top of each other, and nothing in DropR, it shows the answer correct. So is there a way to setup a dropzone to ONLY allow one object. This slide is setup as a Pick One activity as that was the suggestion throughout the discussions for a multiple drag and drop activity.
I hope someone has an answer, and it's relatively simple, because I'm new to Storyline.
