html - Twitter Bootstrap 3.3.5 navbar 下拉右拉

Question

我试图让下拉菜单转到最右边，在搜索输入和提交按钮之后，尝试了 pull-right，navbar-right 但无济于事。

有什么办法可以实现吗？

<nav class="navbar navbar-default navbar-fixed-top">
<div class="container">
  <div class="navbar-header">
    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Project name</a>
  </div>
  <div id="navbar" class="navbar-collapse collapse">
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Home</a></li>
      <li><a href="#about">About</a></li>
      <li><a href="#contact">Contact</a></li>
    </ul>
    <form class="navbar-form navbar-right" role="search">
      <div class="form-group">
        <input type="text" class="form-control" placeholder="Search">
      </div>
      <button type="submit" class="btn btn-default">Submit</button>
    </form>
    <ul class="nav navbar-nav pull-right">
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Login <span class="caret"></span></a>
        <ul class="dropdown-menu">
          <li><a href="#">Facebook</a></li>
          <li><a href="#">Twitter</a></li>
          <li><a href="#">Google</a></li>              
        </ul>
      </li>
    </ul>

  </div><!--/.nav-collapse -->
</div>

真的不确定，但是如果您将登录部分 ul 更改为:

 <ul class="nav navbar-nav pull-right">

到:

<ul class="nav navbar-right pull-right">
