title: Twitter Bootstrap 3 navigation icon doesn't expand in their examples
body: <p>I'm new to Twitter Bootstrap. When I go to the examples for version 3 in both Firefox and Chrome when I shrink my browser window the navigation collapses to the icon with three horizontal lines. However when I click on that icon I don't get the accordian expanding to see the navigation links. </p>
  
  <p>If I view the examples for v2.3.2 it works just fine. </p>
  
  <p>Is there a work-around at this time for v3 or do people recommend using the older version until this is fixed if this navigation feature is something you really need? </p>
  
  <p>v2.3.2 Example that works
