[development] node-specific main-menu

[i...@informatik-halle.de]

sorry for crossposting.
 
Hi guys,
 
is it possible (with drupal 7 or drupal 6) to implement an node-specific menu?
the point is: i would like to display an node-specific main-menu which changes
according to the pages. Example: Menu 1 shows
A/B/C and menu 2 shows ONLY D/E/F.
 
Thank you!
Florian
