In family creation, family parameter doubts

[Anonymous]

I have created one bath set family. It contains vanity, taps and Mirror. These three family created under plumbing category. I have created three family type parameter like Mirror, vanity and taps. But in mirror parameter vanity names also coming because of same category. How to filter mirror names only visible in mirror parameter without changing vanity and taps family category? Is there any formula please tell me. I am a basic learner.

Not really, you could have an integer set the selection I suppose...

This solution suits one family with one common parameter. But in my family 3 different family and how to put this solution?

You could do the same thing three times or maybe use nested family with the possible combinations set.
