Codewalkers.com has a new item posted today with information on a PHP Layers Menu System project over on SourceForge.

Are you looking to make a cool looking navigation menu? Need to make a tree menu? The PHP Layers Menu System has you covered. This excellent library will help you create DHTML menus very quickly. I've just used it to create the new navigational system you see here on Codewalkers.

From the look of it you can make simple, cross-browser drop-down menus with PHP driving the hierarchical structure and dynamically building the information on the fly...
