It is so you can group similar fields together, for instance you could have a group of fields for “Personal Details”, “Home Address”, “Postal Address”, “Company Details” etc…

When you create groups it will automatically add a heading around those fields and to some extent you could apply different styling to each group of fields.

Applying the Groups in Form Design

When you are in Form Creator and editing a field there is an Option called Group.

To add a new group enter it in the input box and Click "Save Field" or "Save & Add New"

To select an existing group select the group from the drop down list.




You can also select existing groups as shown below
