    for(var i=0;i<map.length;i++) {
        let chck = jQuery('<input type="checkbox" />');
        let amt = jQuery('#product_id_' + map[i][1] + '-donation-amount');
	amt.attr('placeholder', jQuery('#product-' + map[i][0]).data('first_price'));
        if (amt.val()) {
	    chck.attr('checked', 'checked');
        }
        let amtdiv = jQuery('#row-product_id_' + map[i][1] + '-donation-group').detach();
        jQuery('#am-product-terms-' + map[i][0]).append(amtdiv);
        amtdiv.hide();
        amt.before(chck);

        chck.change(function(){     
            chck.nextAll().toggle(this.checked);
            if (!this.checked) {
                amt.val('');
            }
        }).change();
    }

    jQuery(".am-product-terms .am-row .am-element-title .comment").detach();

    jQuery('input[type=radio]').change(function() {
      for(var i=0;i<map.length;i++) {
          jQuery('#row-product_id_' + map[i][1] + '-donation-group').toggle(jQuery('#product-' + map[i][0]).is(':checked'));
