    No, there is not a way to achieve this, at least from within the form builder. Field options are static and cannot change according to user actions.

    It may be possible to accomplish this using your own custom scripts, but you'd have to host the form's source codes on your own server. Furthermore, JotForm cannot guarantee full form functionality once you modify its source codes. You'd have to know programming very well in order to execute it properly.
