How to expand the menu to the currently selected sub-category.

Can somebody help me change the CSS of the Collapsing Categories menu widget to auto-expand the menu to the currently selected Category.

The Collapsing Category plugin can show category hierarchies : like this

However when you click a sub-level category such as SEO or Animation, the browser navigates to the Sub-directory however the Menu will not auto-expand the hierarchy to display the current sub-category where the browser is at. Instead it stays like this https://docs.google.com/a/fixxi.net/file/d/0B9EzaG7RrpQ4N0FXbGlwZXpURXc/edit

Here is a “work-in-progress” link where I am trying to get this done http://freelancejobs.fixxi.net/category/internet-marketing/seo/animation
