Can I programatically collapse groups in TimeLine TreeView

Hello,
I have a TimeLine in treeview mode. I need to be able to programatically collapse some, but not all, of the groups. For example, in the attached image how could I programatically collapse the group “Admin”?

Hi,
try scheduler.openSection(section_id) and scheduler.closeSection(section_id)
