[CLOSED] pre-loading a TreePanel BUT only for 1 or 2 levels?

[adrianot]

Hi,

I am going to figure our how to request a TreePanel to load immediately 2 levels (at first load, with a single request), and make the subsequent levels optionally expandable "on demand" when the user clicks on the "expand" icon of a node.

Is it something that can be done somehow?

Thank you.

Hi @adrianot,

You can populate all the nodes in one request.

For example,
https://examples2.ext.net/#/TreePanel/Loaders/Page/

If you configure the root node with Expanded="true", it will initiate a load request for that node. In the request you should return all the nodes for two levels.
