Bootstrap 3 非画布侧边栏菜单，如 Facebook 的

Question

我正在使用 Bootstrap 3 的一些示例作为非画布侧边栏菜单，当它进入移动设备时，可以在此处看到：http://jsfiddle.net/AllenDB/9aAjJ/

如何将画布外菜单调整为类似于 Facebook 的在线搜索/好友在线画布菜单，使其始终从菜单顶部开始并且您只能在其中滚动？与我的示例一样，导航栏是固定的，因此可以切换侧边栏菜单。但是，当您向下滚动实际页面并切换菜单时，您必须向上滚动才能看到链接。我想看看如何将其调整为菜单从顶部开始的位置并将内容和固定导航栏推到一边，同时能够在菜单中滚动而不是内容？

CSS：

    html,
    body { overflow-x: hidden; }
    body { padding-top: 70px;}
    .navbar { color: #FFF; }
    footer { padding: 30px 0; }


    /*
    * Off Canvas
    * --------------------------------------------------
    */
    @media screen and (max-width: 767px) {
       .row-offcanvas { position: relative; -webkit-transition: all 0.25s ease-out; -moz-transition: all 0.25s ease-out; transition: all 0.25s ease-out;  }

       .row-offcanvas-right
       .sidebar-offcanvas { right: -50%; /* 6 columns */ }

       .row-offcanvas-left
       .sidebar-offcanvas { left: -50%; /* 6 columns */ }

       .row-offcanvas-right.active { right: 50%; /* 6 columns */ }

       .row-offcanvas-left.active { left: 50%; /* 6 columns */ }

       .sidebar-offcanvas { position: absolute; top: 0; width: 50%; /* 6 columns */ }
    }

HTML：

        <div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
            <p class="pull-left visible-xs">
                <button type="button" class="btn btn-primary btn-xs" data-toggle="offcanvas">Toggle nav</button>

如果我理解这个问题，我认为您希望侧边栏滚动独立于主要内容。
