Configure the Group Field

This article explains what the Group field is and how to configure it in the Custom Type builder.

The Group field is used to create a repeatable collection of fields. You can use the Group field to create an image gallery, a banner, a list of products, a navigation list, and more.

For example, for a price table, you could create a Group that contains one field for the item name and another field for the item price. The user can repeat the group for every item.

Nested Groups

Nested Groups are not possible. You cannot put a Group field inside a Group field, nor can you put a Group field inside the repeatable zone of a Slice.

The visual builder

When configuring a Group field you'll see the options to set the Field name and API ID.
