Custom select menus need only a custom class, .custom-select to trigger the

styles. Custom styles are limited to the select’s initial appearance and cannot modify the
option's
due to
browser limitations.
Material Select
requires an initialization. You have to add the
.materialSelect() js code to the
select element.
