Need to display lengthy query parameter value in the UI or upon onclick

[spitchaiah1]

Hello,

For one of the APIs in our Dev portal (Apigee-Drupal based) , we need to pass either :

1. Query parameter say (param1) which intakes an lengthy xml string as input

I have tried defining it as query parameter in the Swagger(yaml & json version) but the problem is, in the Dev portal UI, the text box of the query param value field is too small and as a user I wont be able to view/edit this long xml string on the fly - screenshot attached (currentUI.png)

(or)

2. Send this xml string as form-url-encoded parameter in the request body (its a POST request)

Tried defining it as body parameter but there's some issues in displaying xml input string and the form-url-encode on body parameter doesn't seem to work. Code snippet attached (codesnippet_form-urlencode.json)

Preferred experience would be like something similar to Postman RESTClient in which, when we click on the param value, the value field box gets expanded (Eg: referenceUI.png). I'm guessing this may need some UI template change. Please let me know a better way to implement this common behavior.
