I'm sorry but I don't understand what you mean by "empty rows". Are you referring to possible empty rows in the hidden question if less than the max actors is selected? If so, you simply place group-level relevance on the corresponding follow-up question sets like:That being said, we still need a way to hiding the empty rows created that way.
!is_empty(qHidden_SQ001)
So, you have actor-specific images? If so, depending on the image names, you should be able to do something like:We have used HTML in the description of our answer options <img src="">. Is there a way to pipe this too?
<img src="path/to/images/actor_{qHidden_SQ001.shown}.jpg" />
