I'm in the process of having my ecommerce site with about 60 products redesigned. Currently I have my product navigation menu (for categories) on the top in a horizontal bar, but it's very limited space wise (and I don't want to do the javascript dropdowns) so I'm considering switching to having the whole menu to the left side and only keeping information links at the top.
Any one have experience with which type of navigation works best - placed in the left column, or top horizontal bar?
Thanks guys!
