I'm trying to set up a TreeView. My json data from the server has IDs and Parent IDs that contain what the hierarchy is. Root levels have parentId of "NULL". Can I not specify my hierarchy self-referentially like this? Do I HAVE to make an "items: []" sub-structure in my JSON for each parent node?

var ds = new kendo.data.HierarchicalDataSource({
            transport: {
                read: function(e) {
                    //JSON is returned here. Example [{id: 50, parentId: "NULL", name: "abc"}, {id: 51, parentId: 50, name: "xyz"}]
                }
            },
            schema: {
                model: {
                    id: "id",
                    parentId: "parentId",
                    fields: {
                        id: { type: "number" },
                        parentId: { type: "number", defaultValue: 0 }
                    }
                }
            }
        });
