        }

        $("#select2Dropdown").select2(
            {
                data: data,
                width: '100%',
                escapeMarkup: function (markup) {
                    return markup;
                },
                templateResult: dataFormat
            },
        );

        function dataFormat(data) {
            if (data.loading) {
                return data.text;
            }

            return `<div>${data.id}</div><div>${data.text}</div>`
        }

    </script>
</body>

</html>

注：如果没有添加escapeMarkup，templateResult将返回文本内容，不会按html元素显示数据
