How to use Click Ranking with filtering

If you want to make it mandatory to rank all the options that have been selected at a previous multi response question.

You can do it as following:

Add the ranking question as subquestion.

In the Ranking question add the filter "\.a=%" to make sure that only the answers from the multiple response question are displayed here.

In the Answer control add the max. possible answers that could be ranked. In this example we have max 5 answers that can be selected, "rank 5".

In the Ranking question make sure to change the Selection message. And "Hide Next Minimum" and "Auto Next Maximum".

Add a custom error element in your question. With the text "Please rate all items".
