A few things about Foundation 6:<p>You do not need to include the whole javascript, you can include just the things you need. However, there have been problems with webpack and Foundation javascript developers seem to have no clue about what is going on in the JS frontend world, acting like isolated on a moon station, disconnected, what leads to problems with integrating other things.<p>Very problematic is they still have FOUC problems - you have to look for various workarounds, but FOUC out of the box! The menu components and everything related to responsiveness suffer from it. I do not understand how this ever got released.<p>Foundation 5 was ok, but this 6 release is disappointing. The modular handling of menus is a good idea, but overall execution is bad, lots of micro-problems everywhere, it feels not even pre-alpha. Also very monolithic and non-cooperative, ugly to integrate with anything else.<p>I would recommend looking at semantic ui instead, which also has a good react integration, something Foundation designers do not have ever thought about.<p>About the community: the people are great, but Zurb gives them only a totally annoying "forum" that is not able to filter for versions, so when you are searching for things you get all the stuff from previous versions, an information design nightmare, that would be easy to fix, but they do not even seem to have a problem with it - this says a lot about the agency behind it.<p>Also be careful with installing foundation globally: it will overwrite your Foundation 5 binary, if you are using this, be careful. Not a serious problem, but when you still want to use F5 you have to prepare for it! Even with version 6 they still do not have a clue how to handle versioning, this tells a lot about the code quality you will be confronted with.<p>But they have great marketing, the site and everything around F6 looks really great!
