That’s certainly another important issue. I’ve been working around it with custom modals that have lists of items to select as a replacement for dropdowns. It’s tedious but it works for now.
With the filter issue, I don’t see a reasonable way around it unless I try to use conditional visibility on multiple layers of groups. It’s hard to say whether that’s a reasonable approach.
Being able to apply MULTIPLE CONDITIONAL VISIBILITY parameters would solve the problem, and/or enable the option to add and remove components from a group.
