I've been using dropzone.js in some projects recently and configuring options without no problem, but in a new project I was using a recent version of jQuery (3.1.0) auto-installed by Zend Framework 3 and it appears to cause some kind of conflict with dropzone.js version 4.3.0.
I was not able to configure options for my dropzone, it is always using default options.
My solution, of course have been to come back to an older version of jQuery, which is enough for me (1.11.1).
Hope this helps, and if anyone knows the reason of the conflict, cool!
Regards
