Meta fields

FormLinkField

Code
{
  "type": "FormLinkField",
  "key": "related_record",
  "data_name": "related_record",
  "label": "Related record",
  "display": "default",
  "description": null,
  "description_mode": null,
  "required": false,
  "required_conditions": null,
  "visible": true,
  "visible_conditions": null,
  "read_only": false,
  "read_only_conditions": null,
  "default_value": null,
  "allow_creating_records": true,
  "allow_existing_records": true,
  "allow_updating_records": false,
  "allow_multiple_records": false,
  "form_id": "target-form-id",
  "record_conditions": null,
  "record_defaults": null
}

Additional attributes:

• allow_creating_records, allow_existing_records, allow_updating_records
• allow_multiple_records
• form_id: Target form identifier
• record_conditions: Filters for linked records
• record_defaults: Default field mappings when creating new records

record_defaults entries use mappings like:

Code
{
  "source_field_id": "source_field_key",
  "destination_field_id": "target_field_key"
}

StatusField

Code
{
  "type": "StatusField",
  "key": "@status",
  "data_name": "status",
  "label": "Status",
  "display": "default",
  "enabled": true,
  "visible": true,
  "visible_conditions": null,
  "read_only": false,
  "read_only_conditions": null,
  "default_value": "pending",
  "choices": [
    { "label": "Open", "value": "open" },
    { "label": "Closed", "value": "closed" }
  ]
}

StatusField is defined under form.status_field (not inside elements).

TitleField

Code
{
  "type": "TitleField",
  "key": "@title",
  "data_name": "title",
  "label": "Title",
  "display": "default",
  "enabled": true,
  "visible": true,
  "visible_conditions": null,
  "read_only": true,
  "read_only_conditions": null,
  "elements": ["first_name", "last_name"]
}

TitleField uses ordered field keys (preferred) or data_name values. Non-empty display values are joined with ", "; choice fields use their current schema labels, and the result is null when no part resolves.

At the root, TitleField is defined under form.title_field and may reference root fields inside ordinary sections, but never repeatable descendants. The same complete shape can be assigned to RepeatableSection.title_field, where references are scoped to that child-record dataset. See RepeatableSection for persistence and UI fallback behavior.
