I have a Scheduler Hierarchical Grouping similar as https://demos.telerik.com/aspnet-mvc/scheduler/resources-grouping-hierarchical
rather than meeting room in the above sample, I have department name instead. I group a list of user names by department name on a scheduler timeline view.
Is it possible to have a expand/collapse icon to allow me expand/collapse on each department? similar as tree list below
Please advise. Thanks!
