Dropdown "Response content type" in Try-it-out is not present

[michaldo]

The dropdown is present with OpenApi 2 spec
https://petstore.swagger.io/#/user/getUserByName

But is absent with OpenApi 3 spec
https://petstore3.swagger.io/#/user/getUserByName

OpeanApi 2 had "produces":

"/user/{username}": {
      "get": {
        "tags": [
          "user"
        ],
        "produces": [
          "application/json",
          "application/xml"
        ],

Open Api 3 has "response" combination

"/user/{username}": {
      "get": {
        "tags": [
          "user"
        ],
        "responses": {
          "200": {
            "description": "successful operation",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/User"
                }
              },
              "application/xml": {
                "schema": {
                  "$ref": "#/components/schemas/User"

Hi @michaldo,

Thanks for reporting this issue! It appears that the dropdown is rendered but its placement has changed from OpenAPI 2.0 due to the changes in the specification.

As you noted, in OpenAPI 2.0 the available media types were specified by the produces field, which is why there was one dropdown for all responses. In OpenAPI 3.0, media types are defined separately for each response, which is why they have their own dropdown and the one that was there in OpenAPI 2.0 does not appear. In your example, you can see the dropdown for the first response:

If media types are defined for more responses, you'll see a dropdown for each of them:

Given this, I’ll close this issue for now. If I misunderstood the report, please feel free to reopen it.
