jquery - 3 级 metisMenu 元素未扩展回事件选择

Question

我将以下 Bootstrap 导航侧边栏与 metisMenu jquery 库一起使用:

<div id="Sidebar" class="navbar-default sidebar" role="navigation">
    <div class="sidebar-nav navbar-collapse">
        <ul class="nav" id="side-menu">
            <li>
                <a href="/Dashboard"><i class="fa fa-dashboard fa-fw"></i> Dashboard</a>
            </li>
            <li>
                <a href='#'>
                    <i class='fa fa-calendar fa-fw'></i> Diary<span class='glyphicon arrow'></span>
                </a>
                <ul class='nav nav-second-level'>
                    <li>
                        <a href="/Diary/Index?diaryModeId=1">My Actions</a>
                    </li>

                </ul>
            </li>
            <li>
                <a href='#'>
                    <i class='fa fa-pie-chart fa-fw'></i> MI<span class='glyphicon arrow'></span>
                </a>
                <ul class='nav nav-second-level'>
                    <li>
                        <a href="/MI/EntityStatus">Entity Status</a>
                    </li>
                </ul>
            </li>
            <li>
                <a href='#'>
                    <i class='fa fa-cogs fa-fw'></i> Administration<span class='glyphicon arrow'></span>
                </a>
                <ul class='nav nav-second-level'>

                    <li>
                        <a href='#'>
                            Question Admin<span class='fa plus-minus'></span>
                        </a>
                        <ul class='nav nav-third-level'>

                            <li>
                                <a href="/Rule/Index">Business Rules</a>
                            </li>
                            <li>
                                <a href="/Question/Index">Question Bank</a>
                            </li>
                        </ul>
                    </li>
                    <li>
                        <a href='#'>
                            User Admin<span class='fa plus-minus'></span>
                        </a>
                        <ul class='nav nav-third-level'>
                            <li>
                                <a href="/User/Index">Users</a>
                            </li>
                            <li>
                                <a href="/Team/Index">Teams</a>
                            </li>
                        </ul>
                    </li>
                </ul>
            </li>
        </ul>
    </div>
</div>

我在刷新时运行以下代码:

$(function () {

    $('#side-menu').metisMenu();

});

1 级和 2 级选择在菜单折叠然后重新选择所选菜单选项时工作正常。当我选择 3 级元素(例如问题库)时，菜单会折叠但不会重新选择。还有什么我需要做的吗？我的 html 标记是否正确？

对于三级菜单项(或任何级别的菜单项)，您需要确保其所有祖先 li 项都具有 class="active"。
