From the Attribute Groups page, you can delete attribute groups.
You cannot delete the default Other or All attribute groups.
Deleting an attribute group does not delete its attributes from the view or from other attribute groups.
To delete an attribute group, in the Created Groups list, click the delete icon for the attribute group. The attribute group is removed from the Created Groups list.
When you save the attribute group changes for the current view, then the attribute group is no longer displayed on components.
If an attribute does not belong to any of your other groups, it is restored to the default Other group.
