In the php code you can see a sql select where parentId is the received id. You have to build your table with thsi structure: id, int parentId, int ... ParentId = 0 for nodes whose parent is the root of the tree. HTH, Yamil Title: Re: Treegrid Dynamic load Post by: zolotoy on July 28, 2015, 08:17:20 AM I think it's much more than that. It will go to the server if you have loader specified:
loader:function(param,success,error){ ..... } Or url property. If you populate data by other means it wont happen. Can't say it is extremely intuitive. |
