Construction parameters Method description Method Parameters Return Remarks
##(new DenDroGram(AdjacencyList::class))->getTreeData ($node_id);
adjacency data is constructed into a multi-dimensional array Root node id Return array Multi-dimensional Array structure (new DenDroGram(NestedSet::class))->buildTree($node_id,['name'])
NestedSet format data generates a rhizomatic structure tree Root node id, each node displays information Returns html text string View related in dendrogram.php Configure routes such as operating node methods (new DenDroGram(NestedSet::class))->operateNode($action,$data)
Node operations for data in NestedSet format action adds, deletes, and changes identifiers, data node details data returns boolean Note that the view corresponds to the data structure NestedSet: :class
