Here i list some of the best Jquery Navigation Techniques i have come across:
This Navigation provides a great transition effect on a mouse over. Quite Fantastic
Background Image Navigation
This plugin provides a sliding effect and changes the background images for each navigation menu to come up with a smooth sliding transition
Accordion Pull down Menu
The Accordion Pull down menu is a good way to wrap up long content and can be used either as a Check Box( Can open multiple menu’s) or as a Radio Button (Can only open one at a time). The plugin will work only on Browsers that support CSS3. Check out here if your browser supports CSS3
Collapsing Site Navigation
If you want a collapsible image navigation horizontally, you mite wanna try this plug-in.Clicking on one of the submenu items will make the whole menu collapse like a card deck and the respective content area will slide out.
Mac Style Dock Menu
If you are a Macintosh Junkie, you will love this Menu navigation. It can be customized with two options, Top or Bottom.
