JQuery based Category Disclosure List Menu with persistence.

We want a menu with identical functionality to the product category tree menu shown here: [login to view URL] When a user clicks a disclosure triangle within the menu, the menu state is recorded in a cookie. This allows for the menu state to be persistent whilst navigation between pages.? Identical to the [login to view URL] site, the menu must be able to save the state of handle multiple disclosure items. Our site is based on the CMS Interspire shopping cart, and the menu will be dynamically generated. The menu must be flexible enough to handle reordering of categories / list items. Unlike the [login to view URL] site, we would prefer the solution to be done using JQuery (not prototype).? Namespaces must be unique, and not conflict with existing javascript on the page. The solution must be consist of a single javascript file, that we will link to in the HTML head.? JQuery will already be linked in the HTML head.? A static HTML file of our menu HTML code will be provided.? The solution must work in:? IE6, IE7, IE8, Safari, Chrome and Firefox.
