Bootstrap - 导航栏固定顶部在另一个div内

Question

I have a div with width:500px and height:300px in the middle of a page.
I want inside this div to have my navbar-fixed-top. Can you please correct my html/css to accomplish that? Thanks

<div class="container" style="width:500px;height:300px;border:solid black 1px;overflow:scroll">
    <div class="row">
        <nav class="navbar navbar-default navbar-fixed-top" role="navigation">
            <div class="navbar-inner" style="padding:10px">
                <div class="btn-group">
                    <button type="button" class="btn btn-default dropdown-toggle" style="height:70px;" data-toggle="dropdown">
                        <div class="icon-some"></div>Dropdown <span class="caret"></span>

                    </button>
                    <ul class="dropdown-menu">

Based on what you said you want the nav bar with the class navbar-fixed-top to be inside the div, it seems simple enough.

All I did was add a position:relative to the css file for the .navbar class

.navbar{
 position:relative;
}

Here is it working

Now if you wanted the nav to stay fixed in the div as you scroll down the page thats a different story.

Here is the code for that

.container{
    position:absolute;
}
.navbar{
    position:fixed;
    width:500px;
}

and live
