Hi,
I am developing a EV-related online survey, and would like to have a drag-down menu to one of the rows(transport mode) in the Matrix model. This confines the answers into fixed scope and saves the trouble to interpret crazy replies.
Would any one be so kind to share any ideas on how to deliver the function? Many thanks!
