Isn't radio box widget supported?

I don't see any option for radio widget in admin page?

You are right. Radio select's aren't available yet.

Hello! Is this feature not available mainly because technical or lack of time issues? Are you planning on developing it soon or would you be interested in receiving a pull request for this issue?

[MarkusH]

Rather lack of time. If you want to add it, I'm happy to review a pull request.
