Display leaf nodes as folders


#1

Is there a way to specify that the leaf nodes appear and function like folders? Or is it necessary to add a child node to each leaf node and then not display them using CSS?


#2

Unfortunately it is not available to make the leaf nodes like “childfull” if they are “childless”.
You may try to use the dynamic loading mode:
https://docs.dhtmlx.com/tree__increasing_tree_s_performance.html
it allows to display “+” sign for the node that has ’ child=“1” '. But it will try to load these child nodes after clicking the “expand”.


#3

All right. Is there a way to add a class to a node or is there a way to hide a node that is not needed?


#4

Unfortunately such view formatting is not supported, due to the hierarchal structure of the tree.

I found a solution by changing the leaf node image to a folder:
myTree.setStdImages(“folderClosed.gif”,“folderOpen.gif”,“folderClosed.gif”);
