How to create pages like Department

Hi everyone,
I want to create a page similar to the menu that opens when I click at “Departments”.
The page should contain links to other pages.
Is that possible? If yes, can anyone explain to me how to do it?

You can check Menu suite how it is created or you can create also.

I want to create a page, not a menusuite?

Do you know how the menusuite gets displayed in RTC(it is not a page, but what is it?)
