That's the only way I know of from pure HTML - make the top level a
link, which fetches a new page showing the sub-menu.

This means a full page reload for each toplevel menu. A little bit of
javascript in the page will remove that. You should find cut & paste
scripts fairly easily to do this. I believe there is even a Python
script to dynamically generate the javascript - I *think* from the guy
who wrote releaseforge...

All the best,
