Navigation is an important part of web design from a usability perspective. However, links and navigation menus also provide opportunities to improve the visual appearance of the site, or to add some interesting effects. There are a lot of horizontal drop menus around the web today and they are becoming more and more popular. On this website you can see ready-to-use jQuery based navigation with some great effects for implementing on your own website. jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. The menu drops down when you hover over the top items and opens the multilevel submenu. Hover above and feel for yourself, the nifty effect of Lava Lamp. What you just experienced is nothing but the LavaLamp menu packaged as a plugin for the amazing jQuery javascript library. When javascript is turned off in your browser you'll use only pure CSS and unordered lists to create the navigation menu with unlimited levels of pop outs.
