Tree behavious - does it support lazy loading?

The tre component is quite nice, I would like to use it in my project. However, it seems to use a bit different logic as compared to PF tree. First, is there a way to do lazy loading, so that children nodes are only loaded on nodeExpand event. My nodeCollapse is totally ignored. Any help on how to go about this?

Hmm, I’ve overlook this thread. Shame on me.

Up to now there is no lazy load support. Even it is longer ago do you have some code to show your problem?
