如何使引导导航栏项目的宽度等于最宽的下拉项目的宽度?

我正在使用bootstrap(3.3.7)构建带有下拉菜单的导航栏

我需要导航栏项目的宽度与该导航栏项目的最宽下拉菜单项的宽度相同。 我不确定如何进行。 另外,如果导航栏项目本身比下拉菜单项宽,则应拉伸下拉菜单项以使其相等。

我试图以像素为单位设置宽度,但它破坏了代码。

<nav class="navbar navbar-default">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <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="#">Brand</a>
    </div>

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

        <li class="dropdown">
          <a href="#" class="dropdown-toggle active" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Awesome Menu <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">Widest Dropdown Item</a></li>
          </ul>
        </li>

        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">My Menu <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>

        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">This is Widest Menu  <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Action 2</a></li>
          </ul>
        </li>
      </ul>

    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

与笔一样,“超赞菜单”的宽度应等于“最宽下拉菜单”的宽度 和 “我的菜单”的宽度应等于下拉菜单中的“另一个链接” 和 “这是最宽菜单”的宽度应保持不变,但下拉菜单项的宽度应增加以与菜单宽度匹配。
