html - ASP.NET 可折叠导航栏

Question

我无法折叠我网站上的导航栏以便它可以在移动设备上使用

这是我的导航栏的代码:

<div style="padding-bottom: 50px;">
        <header id="main-header">
            <div class="container">
                <a href="@Url.Action("Index", "Home")">

                    <img src="~/ToDo_logo1.png" id="logo" alt="logo" style="width:140px; height:50px;" />
                </a>
                <nav class="main-nav" role="navigation">
                    <ul>
                        @if (User.IsInRole("Admin"))
                        {

                            <li class="@(ViewBag.Linktext == "Venues" ? "current" : "")">@Html.ActionLink("Venues", "Index", "Venues")</li>
                            <li class="@(ViewBag.Linktext == "Events" ? "current" : "")">@Html.ActionLink("Events", "Index", "Events")</li>
                            <li class="@(ViewBag.Linktext == "Bands" ? "current" : "")">@Html.ActionLink("Bands", "Index", "Bands")</li>
                            <li class="@(ViewBag.Linktext == "Admin" ? "current" : "")">@Html.ActionLink("Admin", "Admin", "Home")</li>

                            @Html.Partial("_LoginPartial")
                        }

                        else
                        {
                            <li class="@(ViewBag.Linktext == "Venues" ? "current" : "")">@Html.ActionLink("Venues", "Index", "Venues")</li>
                            <li class="@(ViewBag.Linktext == "Events" ? "current" : "")">@Html.ActionLink("Events", "Index", "Events")</li>
                            <li class="@(ViewBag.Linktext == "Bands" ? "current" : "")">@Html.ActionLink("Bands", "Index", "Bands")</li>

                            <li>@Html.Partial("_LoginPartial")</li>
                        }
                    </ul>
                </nav>
            </div>
        </header>
    </div>

使用此代码，导航链接消失，但我无法让折叠导航栏图标与其中的链接一起出现。

使用 Bootstrap 3 和 MVC，以下内容将为您提供一个可折叠的工具栏和一些经过用户身份验证的测试，以显示您可以删除/玩的东西。

<div class="navbar navbar-fixed-top">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle navbar-inverse" data-toggle="collapse" data-target=".navbar-collapse">

                    <span class="icon-bar navbar-inverse"></span>

                @Html.ActionLink("MY SITE NAME ", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })
