How to create vertical and horizontal menus with RoR

Hi all

I am designing an applicaiton that needs horizontal and vertical menus,
and I would like to know how to create them with RoR

I am looking for something similar to the left vertical menu from
Amazon ( called Browse. And the horizontal menu on top
of the pagewith tabs and links.

Also the horizontal an vertical menus for this web site seems very user

any suggestions?

This is possible with just pure CSS. In Rails you would just assign a helper
method to spit back the appropriate structure. Still there's probably plugins
out there that make all of this a bit more turn-key.
