When you create a group, you give the group a name, select default options for how the group is used, and then select the attributes that belong to the group.
From the Attribute Groups page, to create a new attribute group:
Click +Group.
On the New Group dialog, in the Group name field, enter the name of the new group.
For a group in a base view, to have this group enabled on the Available Refinements panel, select the Include this group in Available Refinements check box.
Note that because the Available Refinements panel only uses base views, this check box is not displayed for groups created in other views.
To have this group enabled when displaying record details information for this view, including on the Record Details and Compare dialogs, and in the default configuration for a Results Table component, select the Include this group in record details check box.
