I am thinking of using typeform in near future and am testing it here: https://www.elimaginario.es/prueba
On the computer everything is ok but on mobile, it becomes a popup. The problem is that main menu is over that popup and, for example, it disables the option to close that popup. I have talked to Typeform people and they say that the only way would be changing the z-index of the main menu so that it gets under the popup instead of on top of everything.
I still have not tried but I am going to use more types of popups soon, so maybe I will have the same problem with them.
Is it possible to make menu go under popups?
