Question
How can I make a field group collapsed by default?
Answer
Field groups have a collapsed property. When you describe the field group, set the true value in the diff section.
An example for the OrderPageV2 schema, "Recipient information" field group.
diff: /**SCHEMA_DIFF*/[ { "operation": "merge", "parentName": "OrderResultsTab", "name": "OrderReceiverInformationResultsControlBlock", "values": { "controlConfig": {"collapsed": true} } }, ]/**SCHEMA_DIFF*/
