title: Make Bootstrap 3 collapsed menu overlay page
body: <p>I was wondering if it's possible to make a Bootstrap collapsed menu show over the page rather than pushing the page downward? I tried giving a z-index on the menu but with that, I had to make the menu use absolute positioning...bad idea. I want to stick with the route Bootstrap takes, but just make the menu overlay instead of push. Any ideas? Has anyone achieved this?</p>
  
  <p>Thanks</p>
