To add a new group, go to the Groupings tab and click on New. This will take you through to creating a new group with several pages of information for you to add as much or a little as you need. All groupings must have a Title, an image and a Grouping Type.
To edit a group, click on that group from the Groupings tab and make any changes from there.
To delete a group, find the group you want to delete from the main Groupings tab, click in the tick box on the bottom right hand corner of that group and click on delete button on the menu bar.
