2.2. Expand / collapse the layer tree
When a layer group contains the ‘multiple layers’ icon it means the layer tree group is expandable and collapsible. To expand a layer tree simply click the group header text (‘Expand this group’) and the group layers shall be opened. To close the layer tree simply click the same text to reverse the process and collapse the layer group.
