Preorder Modified Tree Traversal

Hi all, I'm trying to use "pmtt" to display a windows explorer style view of products in a database. If anyone is familiar with "pmtt" could you send me an email, I'm looking for some help. I built some code to pull the "Levels" out of the database, I need some help tracking which level the user is clicking on so that I can create a drill-down scenario. I know this can most likely be achieved more easily using the adjacent tree method, but I need something a bit more robust than that. Let me know if you have created any systems that are drill-down style menus or whatnot, I'm interested in the methods you used to achieve your success. Thanks All! PS- Thanks to those who suggested the Linux command line HTML 2 PDF package!! Matt Babineau Criticalcode w: http://www.criticalcode.com p: 858.733.0160 e: matt@criticalcode.com
