lozaria Posted July 5, 2011 Posted July 5, 2011 Hi,I'm working on a free app that should be able to add new categories.I'm investigating the ps_category table. I know that level_depth, nleft and nright fields are used for quicker building of the nested hierarchy structure of the Categories. However when adding new category with blank level_depth, nleft and nright it is still visible inside the Categories Block and inside BackOffice.My question is - are level_depth, nleft and nright in Category table required and used at all?Many thanks!
