title: Dropzone previewsContainer initialization
body: <p>I'm using <code>Dropzone.autoDiscover = false</code> and I create my dropzones with <code>element.dropzone()</code>.
  I want to display the processed files in another container, so I used <code>previewsContainer</code> attribute.
  The files are appearing in that container but they're displaying badly, same as when dropzones are not properly initialized.
  So my question is : is there a way to initialize the preview containers?</p>
  
  <p>Thanks in advance,</p>
