I haven't been able to find a simple example on how to configure a tree panel with hierarchical nodes as shown below. I have been able to get the Root and Subroots to populate but I really have no idea how to get the child nodes to populate in the subroots when the tree loads. Could you please direct me to examples or give me a simple code snippet to understand the configuration. Any help is greatly appreciated.
