Delete a Group
To delete a custom group:
Click the Custom Data button at the bottom of the field list.
In the My Custom Data section, select the check box next to the group you want to delete.
Click Delete.
SuperWEB2 removes the group from the list.
If the group is currently in use in the table, then it will continue to display in the table even if you delete the group. You must manually remove the group from the table.
