我从字面上复制了Can't use materialize-select?中的代码，但我认为问题出在其他地方。我也不能使用datepicker，但是Dropdown-navbar之类的组件可以工作，但我不知道。
所以我选择的问题是，它甚至不会显示出来，而日期选择器的问题是，模态内容不会显示出来。
我有一种感觉，就是我在设置中的某个地方犯了一个简单的错误。

您必须关闭此标签：<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js">并创建一个包含您的脚本的新标签脚本
document.addEventListener('DOMContentLoaded', function () {
var elems = document.querySelectorAll('select');
var instances = M.FormSelect.init(elems, {});
});
