title: Bootstrap dropdown-menu is not working
body: <p>Hello my bootstrap <code>nav</code> is not dropping down into different sections like I've seen it in examples on multiple sites. I've tried moving things around but to no avail. I feel like I'm missing something very simple though so any input would be much obliged :D</p>
