There are two selection modes in the Layout view:
Normal: Grouped objects respect the layering of a group of objects. A group has to be ungrouped in order for a single object within the group to be selected and altered.
Flattened: The layers created by object groupings are “flattened” and single objects in the group can easily be selected and altered without ungrouping all.
To select objects:
To select complex items (grouped items) as a single item, click ().
To select and move a single item that is part of a group, click ().
