To select more than one object, press the Shift key and click each one, or drag a selection box around the objects.
2.On the Symbol menu, choose Group.
The selection boxes on each individual object disappear, and a selection box for the group appears around the items.
To ungroup, select the group and on the Symbol menu, choose Ungroup.
