Render only one API action method with swagger ui on fly

I am working on swagger-ui with the help of swashbuckle.net.core code base(https://github.com/domaindrivendev/Swashbuckle.AspNetCore/tree/master/src).i have found that rendering all contoller action method in swagger-ui (index.html).but i want only one action method should be called on index.html from any other html after clicking any link button which is specify the action method name.

1. how to achieve this scenario and
   2.how swagger.json file will render only one action method.
   3.there is any way we can filter based on operationid on group of tag. so that it display only one opratonid api action method.
   4.can we achieve on both server and client code
   please help.

Start with index.html and the Swagger UI configuration, then compare it with the generated swagger.json. Determine whether selecting one operation by operationId and tag requires client-side filtering, server-side document generation, or both. Done means documenting a supported way to display only the requested action method.
