I have a problem with a WordPress website using radio buttons.
At the moment, there are 6 radio buttons, divided in 3 groups: group of 3, group of 2 and group of 1.
The groups have been made like this, because each group required a subtitle in front (in our context, it's a separation between youth, adults and competition playing). Putting all radio buttons in the same group doesn't allow putting the subtitles between the radio buttons.
But having the 3 groups doesn't allow us to enforce a control at registration to check if one of the three groups has been selected, as one of the 6 radio buttons should be selected (as in mandatory).
Has anyone a workaround to either: enable mandatory field check for the 6 radio buttons separated in 3 groups or a solution to put all radio buttons in one group, so mandatory field check is a breeze.
