Main Menu (more than one language?)

[holesovice]

Let me try to phrase this correctly.

Is it possible to change the main menu to different language to the main page?
If someone clicks on (say) a small flag. The page is easy to change. But is it possible to change the main menu to a second language on another page? So say the main pages are in English and then there are pages translated into French with the main menu to match.
Just in case it is not possible and I am waiting time trying.

Thanks, in advance for any help.
