title: Bootstrap dropdown-menu absolute positioning
body: <p>I made vertical dropdown menu in bootstrap. Everything works just fine except one thing. The whole submenu is positioned using <code>fixed</code> attribute, and when there is some more content of page, the whole submenu is scrolling with page. </p>
  
  <p>Here you have example: <a href="http://www.bootply.com/ARlgRwrvQY" rel="nofollow">Bootply</a></p>
  
  <p>Is it possible to fix it?</p>
