Hey,
is there an opportunity to allow multiple responses for radio buttons in
the survey extension (checking more than 1 answer)?
Not if the input type is radio button. You can however make it a dropdown. For instance see the last question here: https://www.mediawiki.org/wiki/File:Survey-dialog.png
