OpenAPI 3.2 supports parent prop. This could be used for generating nested menu for API endpoints.

Good news! We've added support for OpenAPI 3.2, which means the parent prop (and much more) should now work as expected for any valid OpenAPI 3.2 specifications.

OpenAPI 3.2 is backwards compatible with 3.1, so the upgrade should be seamless if you're already running on OAS 3.1.

Give it a try and let us know if you run into any issues!
