Hi Imran,
You can default the expand option by adding code in Refresh method in tree context node class.
Add the below lines of code in Refresh method
lr_root = me->node_factory->get_proxy(
iv_bo = lr_ent
iv_proxy_type = ' child class name' ). you might have already added this code in refresh method, add below line to make it expandable by default.
lr_root->expand_node( ).
Best Regards,
