title: Bootstrap:Fixed nav-static-top on top but scrollable nav-collapse
body: <p>I am using bootstrap to design my site. </p>
  
  <p>Base on this <a href="http://jsfiddle.net/Snippet/Vy2Em/1/" rel="nofollow">fiddle</a></p>
  
  <p>I made the <code>nav-static-top</code> to fixed on top. Now the <code>nav-collapse</code> has to many contents and i can't browse to the last menu because the <code>nav-static-top</code> is fixed on top. Is there a way that the 
  <code>nav-static-top</code> is fixed on top and the <code>nav-collapse</code> content is scrollable so i can scroll to choose on the content?</p>
  
  <p>i've than something like <a href="http://jsfiddle.net/Snippet/Vy2Em/6/" rel="nofollow">this</a> but i doesn't look good
  and i think android devices don't support  <code>overflow:scroll</code></p>
