Is there a sample for multi level DataGrid grouping?

[ttustonic]

For example is it possible (and how) to group mountains (in the DataGrid Sample) first by Range, then by Parent mountain ?

In WPF it was quite easy, add as much GroupDescriptions as necessary, and in XAML add a GroupStyle for each level, but I can't find a way to do it with DataGrid in Community toolkit.

Thanks, Tom
