Ok, look.
Like you can switch Member in my example, you could also switch your QUESTIONS (Previous/Next), then you replace the SWITCH-Button witch a normal SAVE-Button.
So how it would work for you?
You have a lot of questions in your DATABASE. You could then switch with NEXT and PREVIOUS-button all your questions (stored in your database), and with a press on SAVE or CONFIRM, the choosen, question would get active and would be shown to all other USER.
Only if you would confirm your QUESTION-CHOICE, the question would appear for all USER.
Of course you would have to modify the CODE to your needs, but it has a similar principle, like that what you want to do.
The USERS would go to this page, where you show your questions in a LIGHTBOX, SLIDER-GALLARY, REPEATER or just in a normal BOX, MULTISTATE-BOX or STRIPE or what ever.
There are so many options. You could also play with the visibility of the elements…
