To archive a group, click Options under Advert Groups and select the tab called (Un)archive a group.
Select the group that you want to (Un)archive and click Save Changes to confirm the action. Repeat this action in the archive to un-archive a group.
Note:
Sending a group to the archive does not change the status of the jobs contained within it, nor does it archive the adverts within the group. It simply moves the group view into the archive.
