Maybe there is a good reason we dont have this yet. But if its possible, my life would be 10x easier if I could determine visibility based on a microflow that simply returns a true or false.
There is an app for that: https://appstore.home.mendix.com/link/app/2539/First-Consulting/ShowByCondition
I think "conditional classes" is going to be added soon which would allow you to add a class that modifies visibility with a microflow... depending on how conditional classes work. :D
