I am converting a number of sites to top navigation with multicolumn drop downs. Good examples are the navigations on Target and NHL websites. The Target one has over 500 links which is great for SEO but it's also well organized so it's good for humans to. The NHL one only has one multicolumn dropdown but it looks very nice. Are there any good tools out there for creating this or am I looking at a lot of hand coding HTML and CSS? We have looked at Adobe Fireworks but it seemed limited.
