This collapsible and expandable tree navigation system, designed to resemble the Windows Explorer tree, was created to be a simple alternative to more complex and difficult to use systems.

In addition it can be used within frames or outside of them, supports a range of images and works in both IE 5+ and NS6+ (However it does not currently support earlier browsers, and may produce errors. Future versions will include a browser sniffer for more graceful degradation in these cases).
