How does dynamic data loading for trees work?

[dandv]

I've read the guide on loading big datasets for trees but it's unclear how exactly it works.

By sniffing the network connection for the demo, I see that when clicking on a node, Webix sends a request with two parameters:

• continue=true - what exactly does this mean?
• parent=<node ID>

But beyond that, what should the server implementation do?

How does pagination work for nodes with many children? I see there's a pager property for trees but the example is for datatable.

Does loadahead work like for datatable? How about datafetch?

How can a proxy or function be substituted for the url parameter to implement dynamic tree data loading? How does url differ from dataFeed?

It would be great to improve http://docs.webix.com/datatree__loading_data.html with this information; otherwise users may be fumbling in the dark trying to load tree data dynamically.

Is it possible to do page loading for the children for a Treeview? In Kendo UI it's not. DHTMLX can do it via the DistributedParsing option.

All the answers you will be able to find in the updated documentation that comes with Webix 2.2 release.
