Overflowing drop zone
Hi all -
I've built a simple sorting activity and am having difficulty preventing the user from stacking all 7 items into a drop zone that is only big enough for 4 items. I have not encountered this before, so I'm completely unaware of how to prevent it. I see no setting for controlling this behavior, so I would be grateful if one of you could point me in the right direction.
More about the interaction:
- there are 5 phrases to sort (see blue column in screenshot below)
- there are 2 drop zones (RELEVANT and NOT RELEVANT)
- see 2nd image below to see what is happening
Any ideas on how to prevent? Thank you in advance...Paula
