How to show multiple samples in request body of swagger doc?

[foreso-GitHub]

I tried to write swagger doc with mulitple samples in request body but failed.

Here is my code:

@api_v1.method()
def echo(
    data: str = Body(..., examples=['123', '456']),
) -> str:
    return data

And here is what swagger ui doc shows.

What I want is a dropdown combobox which include multiple samples.

Does fastapi-jsonrpc support multiple samples?
