Unless I do not quite understand you I think you missed Anthony Baxter's tree_and_sql howto (http://www.zope.org/Members/anthony/tree-coding-tricks ). It will probably give you either exactly what you want or enough ideas to get you further.

Hi Yes, I looked over that document and unfortunately it doesn't help me. It talks about a *one* file structure where each item in a file can be related to another item. I'm looking at a simple two file structure of records and categories and being able to display those categories in a shallow, two level tree. I've given up for the moment and written my display screen in a way which probably makes more sense but I'd still be interested to know for the future how it works Cheers Ian
