If none of the radio buttons have a checked value the initial state of all will be deselected, until the user interacts with one. I think this would be the expected behaviour in this situation. This can be useful to ensure that a user actually considers their choice or when the question of which option is default is socially loaded – such as gender or sexual orientation. I don’t really get how making it required changes anything in the current setup either – there’s no other choice but to make a selection.
Great plugin btw and thanks for the support!
