Render as a nested list of lists (<li></li> elements in a <ul></ul>). Use a jQuery menu plugin to convert to a dynamic menu.

Normally, I would use a server control for a menu, that would add copies of itself for submenus, making it dynamically generated. However, consider caching it, as it is not quick to generate.
