How might I go about creating related combo boxes, where one has it's options retrieved (via AJAX) when the other one is changed? I've looked at a remote_function call on the parent Combo's :onchange, but it doesn't appear that the parent combo's value is send in the request...? I need the value in order to send back the proper options for the child combo box.
Rather than answer directly, let me recommend the book "Ajax in Action" by Crane, Pascarello, and James.
They go into great depth explaining how to do exactly what you're asking about. While not totally Rails-specific, the knowledge they lay down is great. A must-read.
