I am facing the same problem. For playback, the dropzone selector new Dropzone('#selector') does not work as aspected by default templates. The selector does not work in asynchronous mode. downloaded views. There is an easy fix. Initiating a dropzone on the form will display the dropzone template correctly.
View
<form id="dropzone-form" class="dropzone"></form>
Javascript
var myDropzone = new Dropzone('#dropzone-form', { url: "/file/post" });
