Set up Repeatable Field Links

Link a source repeatable field to one or more dependent repeatable fields.

Configure a source repeatable field to drive one or more dependent repeatable fields, so that adding an entry in the source automatically creates a matching entry in every linked field. See Repeatable Field Links for how linked entries behave when the form is filled in.

Prerequisites

• You are signed in as a Standard Registry user.

• The schema is open in the Schema Editor in DRAFT status.

• The schema contains at least one repeatable field (Allow multiple answers enabled) to use as the source, and at least one more to use as the dependent.

Steps

1. Open the Repeatable links tab

Switch to the Repeatable links tab in the Schema Editor. The tab lists the links already defined for this schema, or shows No repeatable field links in this schema. if there are none.

2. Add a link

Fill in Add repeatable field link and select Add link:

• Source array, the repeatable field that drives the group, for example Project Location.

• Dependent array, the repeatable field that should follow the source, for example Baseline Emissions. It can live in a different schema of the same document.

• Entry display name (optional), a field from the source entry used to label each entry in the form.

Repeat to add more links. One source can drive several dependents, and a dependent can itself become the source for the next link. Build chains top down: add the parent link before using its child as a source.

3. Copy values between entries (optional)

Before selecting Add link, use Add pair to map a field from the source entry to a field in the dependent entry. Pick the Source field and the Dependent field, and the value is copied automatically and shown read-only in the dependent entry. Add as many pairs as you need. They appear under Copied values on the link card, and Remove pair deletes one.

4. Save the schema

Select Save all. Links, entry display names, and copied value pairs are stored with the schema.

Result

The schema stores the configured links. When the schema is used in a policy:

• Adding a source entry creates a matching entry in every linked field, labeled with the entry display name.

• Copied fields arrive filled and read-only, and update when the source value changes.

• Removing a source entry opens a Delete entry confirmation, and confirming removes the matching entry from every linked field.

Troubleshooting

The dependent field still shows its own add and remove controls. The link was not saved. Reopen the Repeatable links tab and check that the link appears on a card, then select Save all.

I cannot add a condition on a field inside a linked entry. This is by design. Fields inside a repeatable group are excluded from the condition pickers because the rule could not be enforced on the server. See Repeatable Field Links.
