title: How to properly add a JS library to a Faveod project?
body: <p>I am trying to add a <code>jQuery Select2</code> formatter to a field and it doesn't work, but it the console I have the error <code>TypeError: $(...).select2 is not a function</code> and the network tab tells me that the requests to get the files <code>select2.min.js</code> and <code>select2.css</code> failed with a 404.</p>
  
  <p>Do you know what could be the problem? Is my project wrongly configured?</p>
