The Moodle Navigation block is disabled on our site. I make my own hardcoded menus in HTML blocks instead (ie. fixed links, not generated).
It would be really amazing to be able to make these collapsible. Just three or four top-level parent items, with one level of links under them, which appear when clicked.
The caveat is that I do not have access to the server, so it has to be pure CSS only - no javascript or Jquery.
I found a couple of little CSS menus online, but they don't work with IE.
Thanks.
