Hello,

I wasn't sure how you wanted to implement the menu dynamically so what I
have done is written a HttpHandler that writes the javascript menu like
the one that Miguel posted.  So if someone can tell me how to get the
children nodes for a given item, then those children can be dynamically
added to the menu.

Currently I have a couple nodes hardcoded, but it would just be a matter
of adding a foreach to add the children items.

There is a screenshot at
