Bootstrap下拉菜单-全宽和中央水平项目

Question

我下面的导航栏具有一个下拉菜单，其中显示<li>元素的水平列表

<ul class="dropdown-menu">

如何确保下拉菜单的行为与div容器类相同？ 即：屏幕的整个宽度与项目集中？

@import 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css';

<nav class="navbar navbar-default">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="true">
        <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-left" href="/home/"><span class="logo"></span></a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="navbar-collapse collapse in" id="bs-example-navbar-collapse-1" aria-expanded="true" style="">
      <ul class="nav navbar-nav navbar-right">

        <li class="">
          <a href="/opt1/">Option 1</a>
        </li>
        <li class="">
          <a href="/opt2/">Option 2</a>
        </li>
        <li class="">
          <a href="/opt3/">Option 3</a>
        </li>
        <li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">More...<span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li class="">
              <a href="/drop1/">Dropdown 1</a>
            </li>
            <li class="">
              <a href="/drop2r/">Dropdown 2</a>
            </li>
            <li class="">
              <a href="/drop3/">Dropdown 3</a>
            </li>
            <li class="">
              <a href="/drop4/">Dropdown 4</a>
            </li>

          </ul>
        </li>
      </ul>
    </div>
    <!-- /.navbar-collapse -->
  </div>
  <!-- /.container -->
</nav>

看一下Bootstrap的Yamm Menu ，这就是您所需要的。
