How do the menus function?

As you have brobably noticed our web-page has two menus. One horizontal at the top that is the "Main menu" and each of the buttons of the main menu activates a submenu at the left side of the page.

So each choise of yours in the "Main menu" activates a submenu that provides usefull information related to your choise.
