If you want have only one of the series of checkboxes or radio buttons to be selected, then you will have to name all the inputs names the same. The values can be different, but the name must be the same. My example is different in that it is more static than dynamic. I needed a selection that would allow the user to choose to check only one or all selected.
You could take a look at what Teo said about dynamic checkboxes:

So this should be entered then in the checkbox group value:
connAccommodation.data.queryAirports.values("AirportID").map("$value.toString()")
