title: Dropdown menu with full width submenu
body: <p>I am trying to create dropdown menu using Bootstrap Twitter. I need to have submenu that has width same as main menu, and is placed below it.</p>
  
  <p>Bootstrap provide us only with standard dropdown menu that is placed right below the clicked li item and width dependent on this li. It is of course understandable as submenu is child of clicked li, but do you have any easy tricks to make it change?
  Or the only solution is to write my own dropdown for this?</p>
  
  <p>What is more, I need it responsive.</p>
