UI document drop-down for multiple swagger documents with swaggerUi3?

[greenmooseSE]

Hi,

I have multiple version documents (.../v1/swagger.json, .../v2/swagger.json) and want these to be disoverable via a dropdown in UI.

I noticed there should be a way in swagger-ui3 to specify multiple urls (introduced via swagger-api/swagger-ui#3261). Is this possible to use with the NSwag swagger generator for aspNetCore somehow, or is there an alternative approach?

Thanks.
