Here's a new JQuery Plugin: Menu Toggle Adder http://code.google.com/p/js-menu-toggle-adder/
It automatically adds "toggle" triangles to unordered list menus for each list item that contains an unordered list. ....It does a bunch of other "stuff", like expanding the nested ul that matches the current url and adds a class to links that match the current url. It's designed to help long, vertical menus on ecommerce websites be more usable. This is my first JQuery plugin. Any feedback is greatly appreciated.
