JavaScript menu in tree-view

My cousin is searching for a simple JavaScript tree menu… or menu bar… something like that, as long as it’s simple enough. Now, I searched Google, but most of them are:

  1. for sell
  2. too complicated
  3. crappy

Does anyone know where I could find him a good example? It has to be 100% JavaScript and for use on a HTML page. PHP is also welcome.

Thanks in advance!! :slight_smile:
