Question

我一直在寻找解决我的特定问题的方案而没有取得多大成功。我试图在bootstrap 3中编写一个网站。我使用了一个反向导航栏，它可以在台式机/笔记本电脑上呈现。

左侧有菜单项，左侧有两个项（注册和登录）。注册指向注册页面，登录结果在下拉登录框中。

但是，我希望菜单在移动设备上呈现为汉堡包，只有当汉堡包被点击时才会显示菜单项。在此菜单中，注册和登录链接可以低于其余的菜单链接。

我开始的代码如下，我已经包含了一个屏幕截图。任何援助都是非常令人沮丧的。

您需要稍微调整类/元素层次结构

<nav class="navbar navbar-inverse navbar-fixed-top">
    <div class="container-fluid">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
        </div>

        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav">
                <li><a href="index.php">Home</a></li>
                <li><a href="">About Us</a></li>
                <li><a href="contact.php">Contact Us</a></li>
                <li><a href="signup.php">Sign Up</a></li>
            </ul><!-- nav navbar-nav -->
            <ul class="nav navbar-nav navbar-right">
                <li><a href="register.php">Register</a></li>
                <li class="divider-vertical"></li>
                <li class="dropdown">
                    <a class="dropdown-toggle" href="#" data-toggle="dropdown">Log In <strong class="caret"></strong></a>
                    <div class="dropdown-menu pull-right" style="padding: 15px; padding-bottom: 10px;">
                        <form action="login.php" method="post">
                            Username:<br /><input type="text" name="username" value="<?php echo $submitted_username; ?>" />
                            <br /><br />
                            Password:<br /><input type="password" name="password" value="" />
                            <br /><br />
                            <input type="submit" class="btn btn-info" value="Login" />
                        </form>
                    </div>
                </li>
            </ul>
        </div>
    </div><!--container-fluid-->
</nav>
