I am very first to this work.
I want to make a data table which is filtered on its column name.
Here is what I want:

I want to click TYPE and there are only "A", "B", "C". So I can see only selected type contents.
umm like this one.
but only in the column name. the highest column.
I am using C#, .NET 6.0, WPF.
Can you show me some simple or complex codes by C# and WPF? I dont know much about it but keep studying.
THANKS
