Right now, we have jquery, angular and chosen-js as normal dependencies.

Especially for angular and jquery, this is a big issue when used with packers like webpack, because it might force the packer to include 2 versions of those huge libraries - the user-defined one in their package.json and ours. This will happen when the 2 versions are not semver compatible, which is quite easy to fall into.

I would say that we definitely want to move those two to a peerDependency.

Edit: As an aside, I'm not sure that we're using jQuery v3+ methods? Any reason for pinning to that instead of ^2.0? chosen-js itself supports ^1.4
