A small bug was addressed today that fixes an issue with Radio button fields. These fields did not respect the "optionality", ie setting the radio button to be required did not work.
This was a result of using radio button "accessory" instead of an"element" input, which we've fixed.
The checkbox element will also be updated to include a required option, and there will be an option to have a default value for this field. This post will be updated when those are released.
