Thanks for filing an issue 😄 ! Before you submit, please read the following:

If you're here to report a security issue, please STOP writing an issue and contact us 
at security@swagger.io instead!

Search open/closed issues before submitting since someone might have asked the same thing before!

Issues on GitHub are only related to problems of Swagger-UI itself. We'll try to offer support
here for your use case, but we can't offer help with projects that use Swagger-UI indirectly,
like Springfox or swagger-node.

Likewise, we can't accept features or bugs in the Swagger/OpenAPI specifications themselves,
or anything that violates the specifications.
