Cocoa "Attribute Inspector" Interface Attribute Constructor

Question

I am creating a Cocoa application and I need a panel similar to the "Attributes Inspector" in Interface Builder. Thus, with large tabs in the top and expandable / expandable groups. Does anyone know how I can do this?

This is an image of the attribute inspector:
