您在<button type="button" class="navbar-toggle" data-toogle="collapse" data-target="#mynavbar" aria-expanded="false">处输入错误，其中data-toogle="collapse"错误，必须是data-toggle="collapse"

这是正确的代码：

<nav class="navbar navbar-default navbar-fixed-top">
    <div class="container-fluid">
    <div class="navbar-header">

        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#mynavbar"  aria-expanded="false">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>          
      <a class="navbar-brand" href="index.html"><img src= "Logo.png" style="width:120px; height:30px;" alt="TestRank" ></a>
    </div>

        <div class="collapse navbar-collapse" id="mynavbar">
            <ul class="nav navbar-nav navbar-right">
                <li><a href="index.html">Home</a></li>
                <li><a href="About.html">About</a></li>
                <li><a href="Features.html">Features</a></li>
                <li><a href="Contact.html">Contact</a></li>
            </ul>
        </div>
    </div>
</nav>

为什么导航栏下的折叠选项不能在bootstrap3中工作？
