管理员在侧栏多级菜单上悬停效果

Question

我在AdminLTE的侧边栏多级下拉菜单中添加了悬停效果[默认操作是点击展开]

哪个有效，但问题是如果进入3级，跳出外形就折叠了整个菜单，这不是我想要的，如果我跳到3级之外它应该只会崩溃3级而不是1级和2。

这里是js代码：

$('.treeview').hover(function () {
    var _this = $(this);
    if(!(_this.hasClass('active'))){
      _this.addClass('active');
      _this.children().find('treeview-menu').addClass('menu-open');
    } else{
      _this.removeClass('active');
      _this.children().find('treeview-menu').removeClass('menu-open');
    }
  }) 

这就是HTML的结构：

<ul class="sidebar-menu" data-widget="tree">
        <li class="header">MAIN NAVIGATION</li>
        <li class="treeview">
          <a href="#">
            <i class="fa fa-share"></i> <span>Multilevel</span>
            <span class="pull-right-container">
              <i class="fa fa-angle-left pull-right"></i>
            </span>
          </a>
          <ul class="treeview-menu">
            <li><a href="#"><i class="fa fa-circle-o"></i> Level One</a></li>
            <li class="treeview">
              <a href="#"><i class="fa fa-circle-o"></i> Level One
                <span class="pull-right-container">
                  <i class="fa fa-angle-left pull-right"></i>
                </span>
              </a>
              <ul class="treeview-menu">
                <li><a href="#"><i class="fa fa-circle-o"></i> Level Two</a></li>
                <li class="treeview">

                    </span>
                  </a>

这里是working demo的相同内容。只需将鼠标悬停在多级下拉菜单上，然后转到第3级并尝试将鼠标移开，它会折叠整个菜单，我无法检查其下的其他子级菜单

跳过你理解这个问题。

我该如何解决这个问题？

提前感谢您的帮助。
