Most hierarchical menu scripts seem to work on the principal of having a
javascript array of links that are then written to a part of the
document using dom. This as far as I can understand goes against the
guiding ideas of xhtml, it's simple enough to toggle on/off visibility
of particular content, but to control a multi-level menu seems to
require this dynamic document manipulation; anyone have any ideas how a
multi-level menu in the right spirit of xhtml could be controlled?
