A small, solid jQuery plugin which is quite easy to use. It’s a menu which can be used with or without JQuery. What’s special about this script is the included plugin jstorage.js (which is some amazing work btw) to store the current item. So if you’re navigating around, the selected item will stay highlighted. This will spare you some server-side code. You can try this one by clicking on the menu item “File -> New”.
