Yes, it's a tab control. A Tab control is called a "Registerkarte" in German.
To answer the question, I do believe you can set which items are visible and which are not by using a property node of the tab control (Registerkarte).
Make a property node of the tab control terminal and have a look at what you find there.
Hope this helps
