You can change the record title for linked record fields on the form, or records in the portal to something different by going to:
For a linked record field on the form:
Select the linked record field
Go to View
Set Record title to Select another field
Set Custom field for record title value accordingly
For a table/view in a portal or shared view:
Tables
Views
Under Default Fields, set Record title to Select another field
Set Custom field for record title value accordingly
If your views are set to use custom fields or fields from an Airtable view, this will hide the table's actual primary field from miniExtensions.
If your views are set to override default view settings (under the View Type section of your view's settings), you'll need to change this setting on a per-view basis (under Record Title), instead of just in the default fields settings.
💡 Note: Attachment fields and linked records field types cannot be selected for this feature.
Troubleshooting
When Record title is set to Select another field, you must select a Custom field for record title value before publishing. miniExtensions will block publishing and identify the affected linked-record field or child form if the custom title field is missing.
If an already published extension shows “Could not find a primary field for the table” check every linked-record field that uses Select another field and make sure a custom title field is selected.
