You may be experiencing some caching problems. Also around the time you checked I was in the middle of pushing the swift site to Heroku so that may have introduced some issues as well. The new site has a "Create" button with no drop down — Can you please re-try https://www.gitignore.io/.
OK, I tried it at home. Another PC, another Provider, Chrome Version 56.0.2924.87, no uBlock, I even tried it in Inkognito Mode. The result is the same. https://imgur.com/a/Bo4Kq
I'm on Chrome Version 55.0.2883.87 m on Windows. I turned of uBlock Origin for your site.
