Manually add "allow one item per target" in a free form pick one slide?
Hi all- I have a client who wants a drag & drop interaction where a target has more than one item to be dragged to it. I searched the archives and found a brilliant hack where one uses the freeform Pick One question type to allow this feature.
However, my problem arises on the second attempt when the learner tries to fix any incorrect choices. When one tries to switch answers, rather than kicking the previous, wrong answer out of the target, the new choice just gets placed on top of the previous answer. I need to find a way to manually create the "allow one item per target" that is used in a traditional D&D interaction.
I've attached my story so you can get the gist of it.
Thanks in advance for any help!
