I was watching a video about Bootstrap 3 on Youtube. I have Dreamweaver CC and I noticed that I don't have the Bootstrap 3 Grid tab like the user does in the video.
How do I get that tab as shown at the beginning of the video Using HTML5 Parallax Slider on Responsive Bootstrap 3 Pages - YouTube
The UI for the Bootstrap 3, that you see in this video is provide by the DMXzone Bootstrap 3 extension. So - in order to see it, you need to have this extension installed.
The Bootstrap 3 integration in Dreamweaver does not offer such a great UI
