Is there a way to populate children of a node only when said node is expanded #9

I'd like to start off by saying I really like this feature.

One scenario I have is the structure I want to represent with this tree can only be built up via recursive calls across a network. This is very long winded particularly since I may not need all of the nodes being retrieved. One way I would like to do it is by attaching a delegate to an attribute. Ideally this could be something I could cache so further collapse and expand interactions of the same node do not need to go back to the network.

Is something like this possible or feasible?

Nevermind, I figured it out

Used st.session_state to store the tree_select component. If it exists in the session state, any expanded nodes, call the "get_children" method or whatever on those, cache the results of the "get_children" method and bobs your uncle

TL;DR lack of talent for easily confused developer
