You can also add or remove layers in a layer group with the Layers table. When you select a group in the Groups table, the check boxes in the Grouped column of the Layers table indicate the status of the layers. If the check box is set, the layer is a member of the group that you selected in the Groups table. If the check box is cleared, the layer is not a member of the group.

You can select a group from the Groups table to display the layers in the group in the Groups table. To select a group, you must click the button on the left side of the row for a group. You can use the Description column to add a description to the layer group. Typing a name of an existing layer group makes that group active. You can then add or remove layers in a group.
