Verticle or horizontal nav bars?

[Ace02]

Just wondering, in your opinion, which do you prefer?

horizontal for up to 5 or 6 items, vertical for anything above

Yeah I agree. Horizontal navigation is fine when you dont have that many top level sections but anything more and you have problems. Personally I like top level nav horizontally and sub at the side. It kind of visually demonstrates the hierachy of a page:

LOGO - The top level
------------------------------------------------------------
the main sections appear in a horizontal bar
-----------------------------------------------------------
Page title

• sub nav
• down
• the
• left
• hand
• side

Goes from Site level (logo) down to children objects when you scan top to bottom of the page
