Grouping of fields
How to group fields in a form.
Fields can be grouped in a form. This is useful when you have a multiple fields and want to group them logically. A simple group of fields will look like individual fields visually, but the whole group can be treated as one when using dynamics to show or hide fields, and when setting up a Summary you can reference an entire group of fields instead of each field individually.
Groups get really powerful when you configure a group to be a repeating group. This allows you to repeat a group of fields multiple times in a form, such as allowing a user to add and remove multiple addresses.
