移动版本中的菜单打开并工作，但单击菜单项后导航栏不会折叠...我从引导站点获取了 css、js 和导航栏：
问题出在哪里？

</body>//我已将 data-bs-toggle='collapse' 添加到主导航栏，如上所示。
我认为按钮需要一个目标来折叠，所以我添加了 data-bs-toggle='collapse'
它对我有用。希望你也一样..
将其添加到您的标签中。它要做的是，触发汉堡包按钮上的单击事件，这将导致菜单折叠。
<script>
jQuery(document).ready(function($) {
$('.navbar-nav li a').on("click", function() {
console.log("menu clicked");
$('button.navbar-toggler').click();
});
});
