Creating a cascading menu in Dreamweaver

I am trying to create a simple cascading menu in Dreamweaver. I want
it to look similar to the way Microsoft Explorer displays folders and
files so when the reader clicks on one of the topics it will open into
a sub-menu, but once another topic is clicked I want the previous one
to close. PHP Website seems to offer what I am looking for but it's
templates seem to be incompatable with Dreamweaver. Is it possible to
do this using the Macromedia MX Studio software?

Many thanks
