jQuery Drop Down Menu - Version 1.0 The most important part of designing a new site is the navigation or menu system, but this can be tricky, time consuming and often frustrating. You need something that will fit into your design and most importantly, allow your readers to navigate with ease. jQuery Drop Down Menu is a multi level, CSS list based menu powered using jQuery that makes website navigation a smooth affair. And that's a good thing given the important role of this element in any site. And thanks to jQuery, a configurable, sleek "slide plus fade in" transition is applied during the unveiling of the sub menus. 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.
