title: Full width drop up sub-navigation Bootstrap 3
body: <p>I'm trying to create a footer menu with a drop up and full width sub-navigation for mobile devices with Bootstrap 3. I already create the drop up with some css and made the sub-navigation align to the left (I don't know if this is the best way but it works) I've been trying a lot of ways and checking a lot of examples, but I can't figure out how to made the sub navigation cover the full width of the screen.
  Here is my example working in this Bootply <a href="http://www.bootply.com/7wy0Oten9m" rel="nofollow">http://www.bootply.com/7wy0Oten9m</a></p>
