我想创建一个带有嵌套子菜单的下拉菜单，以便当用户在子菜单上显示其下拉列表时，当鼠标从子菜单中取出时，它应该隐藏其下拉列表。我试过但它只适用于click（）方法但我想在hover（）上使用。这是我的代码 HTML

然后是我的jquery
$('a.test + ul').css("display","none");
$('.dropdown-submenu').css("position","relative");
$('.dropdown-submenu .dropdown-menu').css({"top": "0","left": "100%","margin-top": "-1px"});
$('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
// Avoid following the href location when clicking
event.preventDefault();
// Avoid having the menu to close when clicking
event.stopPropagation();
// Re-add .open to parent sub-menu item
$(this).parent().addClass('open');
$(this).parent().find("ul").parent().find("li.dropdown").addClass('open');
});
请帮帮我！感谢。

你可以通过简单地使用CSS来实现这一点 -
.dropdown-submenu:hover .dropdown-menu {
display: block;
margin-top: 0; // remove the gap so it doesn't close
}
