Multiple categories in View Filter Create rule

Hello Everybody,

I am new to this forum
I created a Dynamo file with wich i can create and place view filters in revit with one category.
Is it possible to put multiple categories in view filter and if this is possible how to get that done?

Hope that anybody can help me
I posted some pictures of the created file

did you try feeding in a list?

Do you mean creating list this way?

If i create a list this way i get the following error with the View filter create rule

Duct Accessories don’t have Type Name. The problem is with your category, not your list.

you just have to make sure that BOTH categories have that parameter. That’s not any different than what standard Revit UI does and does not allow you to do.

It worked!!

Thanx for the help

Is it now this posted is solved or how you may call it, it has te bel colsed?
