uncover form elements with qrcode

Hello (i cze?? ?? )

I’m trying to do something rather unconventional, but it might be useful in other use-cases and maybe you would have some advice on whats the best way to do it.

We’re running a workshop for youths, and have to ask some questions. To do it in a less boring way they will get a qrcode displayed every once and again directing them to a form with said questions. Ideally we’d have all of them in a single form, without showing all of it straight away, but after a certain offline activity/qrcode (there’s a gamification element here run by the trainers).

For now we’re just asking for a name each time, and have no way of automatically combining the results. I’ve played around but can’t figure out a way either reload earlier questions “uncovering” new ones on a new page, or use qrcode to “uncover” a new section.

If you’d have any pointers that would be greatly appreciated.
