Overview
A group fieldtype is a simple container that holds additional fields you would like grouped visually as well as under a parent key.
Data Storage
In the screenshot above, the data structure for these fields will be as follows:
location: address: 123 Main Street city: Schenectady zip: 12345
Templating
All fields inside a Group will be scoped under their parent key like so:
{{ location:address }}, {{ location:city }}, {{ location:zip }} <!-- Will output... -->123 Main Street, Schenectady, 1234
