CategoryAttribute in c++/CLI

I read code and fuond the word CategoryAttribute.

What is a CategoryAttribute in c++/cli?

While I think it's clear, I have a few seconds to answer.

It's a CLR attribute class (a modifier available through reflection) that specifies which category/grouping the property should be listed under in a property grid view. Like when you're editing a form, the thing that you change values in like Text, Size, Docking, etc.
