I need to create a question that contains rows of items. The student must only put an answer under the items that fulfill a certain criteria, leaving all others blank. I could use multiple drop-downs, but that requires the student to select EVERY item and select either a blank response (which I don't think Canvas allows) or the correct label. It would be less confusing to have them only select the items requiring a label.
I did try using a multiple answer, but the correct answer can never be blank, which in this case there would be many.
