Help with a survey design problem?
How do I implement a survey where a user, having selected an option from a main menu and answered the questions based on that option, can return to a menu and select additional options? I want all answers to be recorded. So the user can select one or more options, but not at once from the main menu. Only if he answers the questions from the option first.
I should specify that I am perfectly fine with coding this in a programming language (say R, Python or C++) but is there an online tool that could be used to do this? Google forms does not seem to have this capability as far as I know.
