For an app I built with a Section tree, I used a single parent node, "root" with a NULL parent_id. When fetching a threaded list, top-level Sections, etc. I used 'Section.parent_id IS NOT NULL' in the conditions. To have Cake create an empty option at the top of your select element, use 'empty' => true in the params. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CakePHP" group.
