I’m trying to dynamically load subnodes (from a database through a java servlet request that serves data in json format) on expand event in a treeview.
How can it be done? The documentation doesnt such a topic or I couldnt find it.
Can I put the expand “+” icon only on nodes that I know they have children?
I mean how cand I transmit a “haschildren” flag to a node in the json data?
