Section groups allow you to organize your sections in folder-like categories.
Let's say you have a section called "Scope of Services" for design, development and marketing projects. You want to call all three sections "Scope of Services" but make it clear which one is for which services.
You can create all three sections with the same name and then create three different section groups to store each section within.
You will want to create a group for "Design", "Development", and "Marketing".
Do to that, click on the "New Group" button in the content library. Name your groups and once it's created you can drag a section from one group to another.
You can edit a group name simply by clicking on the name. You can also delete a group. If you delete a group with sections in it, all the sections will be moved to the default group.
You cannot edit the name or delete the default group.
You can expand and collapse groups by clicking on them to show and hide their contents.
