It would be nice to have a feature similiar to page skip logic but for individual question or a set of questions (as subform).
My use case is that I have a question like " 1) Do you have ...?" with choices "yes" and "no". Then I have a more precise questions (1.1 and 1.2) if user answered "yes". If user answered "no", then the questions (1.1 and 1.2) should be invisible for the user so that he can skip directly into the question number 2.
Very timely question. We'll actually be adding "question skip logic" in our Aug 25th release (less than two weeks). It will allow you to do exactly what you want.
