How to ensure only one checkbox checked at a time in multifield?

Below I have a multifield for a tab component and obviously at a time only one tab can be active, therefore the requirement is to have only one of the checkboxes checked at a time.

In this scenario there's only one checkbox. Radio buttons also have the same problem since each radio button in a multifield behaves independently and does not check for the status of other radio buttons in other multifields. Does anyone have a working example where this single checkbox validation occurs?
