Grouping layers on the canvas allows you to move multiple layers at once without changing their positions relative to each other. It is important to note that editing is done best when layers are not grouped together, and that grouping is primarily for canvas movement.
Select the canvas layers you’d like to group together. To select multiple objects, you must hold down the Shift key. The selection border should encompass the space occupied by all layers desired to be grouped.
Select the “Group selected items” icon from the menu on the right side of your screen. Now, these items will be treated as one group.
Select the “Ungroup selected items” icon from the menu on the right side of your screen. All items in the group will be removed from the group.
