Common Navigation Menus
Top Bars
Sites that are not too wide or deep may not need complex navigation. A simple menu bar with or without a search feature is sufficient.

Bars with secondary navigation that appears below either in the same form as the tabbed menu secondary navigation or drop down boxes is probably the second most common form of navigation menus on the web.
