I made a mistake on a quiz and asked for three items correct in each of two categories such that students were supposed to drag three items into a list under the first sentence and another three into a list under the second sentence. But, the quiz is (of course) only accepting the three in the specific order I entered them as correct. Is there any way of accepting multiple responses in each box so that I can accept each set of three dropped in any order?
I don't think you can do that with any question type in core Moodle, but you can with my gapfill question type.

You can drop lion or tiger into each column in any order, but if you drop the same thing in twice you only get one mark.
