Robot-friendly Expandable Navigation
This is something I did for the admin area of a couple sites, where they had for example categories and subcategories to manage. It allows the subcategories to be displayed underneath the parent category, and you can expand or collapse each parent category. A little javascript and CSS rules are used to make this work.
The orange colored links don't do anything. The demo is just to show how the categories can be expanded and collapsed.
One big advatage of this technique is that all the text and links are actually on the page and would be readable by any robot that visited it. Most javascript menus hide the links and content away in the javascript.
