谢谢！！
解决方案
只是因为position:relative.
说明
将 position: relative CSS 添加到 .dropdown-item 类，因为您的 ::after CSS 在没有 position:relative 的情况下不起作用.
从 .dropdown-submenu 类中移除 position:relative CSS 因为它从它的 height 计算 top.
$(function() {$("ul.dropdown-menu [data-toggle='dropdown']").on("click", function(event) {event.preventDefault();event.stopPropagation();//方法2:从所有父母的所有兄弟姐妹中删除节目$(this).parents('.dropdown-submenu').siblings().find('.show').removeClass("show");$(this).siblings().toggleClass("show");//在导航关闭后全部折叠$(this).parents('li.nav-item.dropdown.show').on('hidden.bs.dropdown',
