title: A simple collapsable navigation with Bootstrap 3
body: <p>I thought this would be pretty simple, but I've not yet managed to get it to work. The following example looks just like what I want, but it pertains to Bootstrap 2.3. I am having trouble getting it to work in Bootstrap 3. What differences should I be aware of when implementing this for version 3?</p>
