Jquery 引导-响应导航栏工作不正常

我有两个

导航栏，A和B，最初，当你将浏览器缩小到
最大宽度：767px
B设置在A的顶部，
我需要在B的顶部设置一个
，这是我的答案，我选择
css
答案，但当你点击按钮显示
narvars
的内容时，它出现了一个小故障，
A
保持在同一位置，但
B
移动到
A
下方，这不是所需的功能

为了让事情更清楚。。。我将以图形方式显示它：

单击按钮以显示导航栏的内容之前

单击按钮以显示导航栏的内容后

最初
主菜单
位于
标题
的顶部，这一点在下一个
CSS
类中更改：

.navbar-left {
    position: relative;
    top: 88px;
}
.navbar-inner {
    position: relative;
    top: -44px;
}

以下是现场演示：

我愿意接受任何解决方案，包括
jquery
对
css
导航系统的更改

这是我的自定义
CSS
：

body{
    border: solid;    
}
.navbar {
    margin-bottom: 3px;
}
.btn-group {
    float: right;
