[Plugin: Contact Form 7] Make Radio Buttons Required

I have this same problem. It does not allow to make radio as a required field (which is, i think, a major flaw to this otherwise awesome plugin)…

Found a workaraound for this.

You can put one radio button selected as a default by adding default: to the tag. For example: [radio valinnat default:1 “Liityn seuraan” “Eroan seurasta”]

So, you have one already selected and user has to react to that…
