Hello @funkydmtl,
Why not use radio buttons instead checkboxes if you want emulate radio buttons?
A possibility would be insert a “HTML Content” field in the form with a piece of code similar to the following one as its content:
<script>jQuery(document).on('change', '[type="checkbox"]', function () {
var e = jQuery(this),
i = e.attr('id');
if (e.is(':checked'))
{
jQuery('[id="' + i + '"]').prop('checked', false);
e.prop('checked', true);
}
});
</script>
I’m sorry, but this modifications are not related with the plugin, it is pure javascript, if you need additional help you should request a custom coding service through my private website:

Best regards.
