Hiding specific columns in a side-by-side Question and applying force response

Context: I have a side by side question, where users have to rank from 1-4 for various cars on different parameters! Now I have a multiple choice question to capture which cars are owned by the respondent - I have to hide the respective columns based on response from multiple choice question Thanks to @TomG, I have read many of his previous answers and my approach here is: 1. Capture the response from the multiple choice as embedded/ piped text 2. use Javascript to hide the respective cells - $('QR~' + qid +'#2~1~1').up('td').childElements().invoke('hide'); - and header - $('question2QID417' ).childElements().invoke('hide') - ! I have applied force response for the entire side-by-side question; when I hide some of the columns, the question still prompts for some response for the hidden columns. I guess this can be handled by 1. auto-populating the hidden columns with dummy values in the side-by-side question - Please advise how this can be done Also, can someone validate this approach for hiding selective column is correct / is there a much simpler option for this !
