In drupal 5.x,drop down horizontal menu with the nice_menus module

Hi, everyone, hope you will be willing to give a hand here.
I've just tried the nice_menus module which adds that drop down DHTML functionality
to a drupal powered site menu. For who hasn't tried the module it basically generates a
javascript drop-down style menu for the navigation.
I really need a menu that works like the ones I get from the nice_menus module but I
need it to be horizontal.
Would there be a way to bring the navigation menu just below the header of the page
and have it do be a drop down menu?
Can anyone tell me how I could achieve this kind of result?
suggestions are well accepted!

thank you
