[Typo3] Two different menu's on one page

[Michael Medenblik]

How can I create two different menu’s on one page? The first menu has 
to be a horizontal graphical menu, meant to open items in a iframe, 
which  is located on the  main page. There should not be any main 
menu or pages items listed here. The main menu on the left part of 
the site (vertical, graphs) will show the webpages as they are 
listed.

Thanks,
Michael
