Asp.net mvc 4 大屏幕上的两个引导菜单折叠问题

我在页面上有顶部菜单和左侧菜单，我想这两个菜单都应该在小屏幕上折叠，这些在小屏幕上工作正常，但在大屏幕上两个菜单都不显示

<!-- Fixed navbar -->
    <div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
      <div class="container nav-main">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#first">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>

             <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#sidebar" role="complementary" >
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>

请告诉我我做错了什么

为了更正链接的位置，我更改了导航栏元素的顺序，先是左侧，然后是右侧（这不是问题，这是组织问题）。在导航和页面标题之间添加了分隔符。将左侧导航栏项目的类别更改为：

<ul class="nav navbar-nav navbar-left">

而不仅仅是

<ul class="nav">

以下是最后一个JSFIDLE：

我知道这很简单，但如果你打开窗口，你会发现它工作得很好
