I am making use of the datatree component and it shows some unwanted behavior. Is it possible to make a snippet at http://webix.com/snippet that simulates dynamic loading data from backend?

You can use data urls from any sample in the http://docs.webix.com/samples

For example http://webix.com/snippet/76d5c489

data_dyn_json.php goes only 2 levels deep. I need something with at least 3 leves.
I tried putting url to my own server but it that not work

You need to allow CORS for such URL.
