Maybe Ron Savage's CGI::Explorer module might be of use. From the readme:

    CGI::Explorer is a support module for CGI scripts. It manages a
    tree of data, so that the script can display the tree, and the 
    user can click on a node in the tree to open or close that node.

    Opening a node reveals all children of that node, and restores
    their open/close state.  Closing a node hides all children of
    that node.

As an aside for anyone who is interested, Ron's site has lots of interesting Perl material including a series of tutorials.

John.
