Select doors from different groups using dynamo

[julianv4]

Hi

I need to create a “doors and windows chart”, but all of them are in groups, i cannot select them one by one. So i need ideas about how can i select only the elements i need using Dynamo.

Some ideas? I am trying this but without results

Would you try this?

Sometimes your input name could be not as same as element name because of spacing or etc…

Also “List.FilterByBoolMask” list input should be elements not string.(Blue Cloud)
