It is a bit disturbing that this has been posted for a month without any reply.  Is the TreeList not supported by Telerik?

Hello, Joel,

The Kendo UI Team did not answer the question as the client does not hold a valid licence. We respond to clients who hold licences with priority as follows:

-  private support tickets with pre-screening and phone support (up to 4 hours confirmation and up to 24h response)
-  private support tickets (up to 24h)
-  lite support private tickets (up to 72 hours)
-  forum threads (up to 48 hours) 

https://www.telerik.com/purchase/aspnet-core-ui#configurator-progress-kendo-ui-asp-net-(mvc-core)-developer-license---lite-support



The Kendo UI TreeList for ASP.NET Core is supported and a very popular widget in our suite.

You can find the official demos here: https://demos.telerik.com/aspnet-core/treelist/index
The documentation is available here: https://docs.telerik.com/aspnet-core/html-helpers/data-management/treelist/overview

Let me know in case you have a specific question about the widget and I would be glad to assist you here in the forum thread or via a private support case..

Kind Regards,
Alex Hajigeorgieva
