简单菜单不在新行开始 -- BootStrap

Simple Menu not starting on new line -- BootStrap

我正在努力学习 bootstrap 并且对基础知识感到非常困惑 我有这个菜单。当它处于移动模式时,会出现三个堆栈栏,但菜单从 header 行开始。期望的结果是从 header 下面的行开始。我错过了什么 class 或我做对了什么

感谢您的帮助。

试试这个,我已经为右侧的导航栏添加了一个 ul 定义。更改了调用数据目标的方式(仍然是新的,所以不知道是否需要)

    <div class="navbar navbar=default navbar-inverse navbar-static-top" role="navigation">
        <div class="container-fluid">
        <div class="navbar-header">
            <a href="#" class="navbar-brand">Mike's Site</a>

            <button type="button" class="navbar-toggle collaspe" data-toggle="collapse" data-target="#navHeaderCollapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
        </div>

             <!--do we need collapse and navbar-collapse-->
            <div class="collapse navbar-collapse" id="navHeaderCollapse">
                <ul class="nav navbar-nav">
                    <li><a href="#">Home</a></li>
                    <li><a href="#">Blog</a></li>
                    <li><a href="#">Social Media</a></li>
                    <li><a href="#">About</a></li>
                    <li><a href="#">Contact Us</a></li>
                </ul>

                <ul class="nav navbar-nav navbar-right">
                    <li class="dropdown">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false"></a>
                        <ul class="dropdown-menu" role="menu">

                        </ul>
                    </li>
                </ul>
            </div>
        </div>
