Apple Motion 4 - Manual (Page 356)

When a layer or group is collapsed in this manner, it still appears in the Canvas window.
Unlike enabling or disabling tracks, collapsing and expanding the Timeline layers list is
only an organizational tool to help manage the view of the Timeline.

µ
Click the disclosure triangle to the left of the layer or group name. If no disclosure triangle
is present, that object cannot be collapsed or expanded any further.
Adding and Deleting Groups in the Timeline
Motion allows you to add and delete groups directly in the Timeline layers list. If nothing
is selected in the list when a new group is added, the new group appears at the top of
the list. If an object is selected, the new group is added directly above the selected object.
