I am currently on Version 2.1, Build 2111. I started developing this site on Version 2.0 and used pulled in the Coffeegrinder DDP grid system to build it. Looking back, I wish I would have used Bootstrap or Foundation, but I was just starting out and didn't quite understand the impacts.

I see that Bootstrap has a component for Navigation with Drop-Down Menus. I thought I could export it to my PC and import it to my website developed with Coffeegrinder. It wants me to log in, but I'm not using the Coffeecup hosting site. Am I doing something wrong or can't I use that component the way I'm set up?

For some reason you do have to log in, at least to your free account, or find the files in your c drive.
You can't import the Bootstrap component into a non Bootstrap project. You will need all other other files and javascript that comes with the framework.

After logging in, I see that it just exports to the free account. So, it sounds like I will need to convert to Bootstrap.
