title: Change toggle direction
body: <p>I'm using the bootstrap 4 Alpha 5 and I have the default navbar with a toggle menu. This is great, but i'm wondering if it's possible to change the direction of the toggle. Now the menu is getting visible from top to bottom. I would like change this to "left to right", so it looks like the menu is floating from the left side of the screen.</p>
  
  <p>If possible, I prefer not to use third party libs.</p>
  
  <p>Thank you.</p>
