Multiple Dropzone in a single page

It's possible, but you can't bind a second dropdzone on the same element, as you did. 2 Dropzones on one element makes no sense. 2x document.body in your solution atm. Try this...

HTML:

<form action="/file-upload" class="dropzone" id="a-form-element"></form>
<form action="/file-upload" class="dropzone" id="an-other-form-element"></form>

JavaScript:

var myDropzoneTheFirst = new Dropzone(
        //id of drop zone element 1
        '#a-form-element', { 
            url : "uploadUrl/1"
        }
    );

var myDropzoneTheSecond = new Dropzone(
        //id of drop zone element 2
        '#an-other-form-element', { 
            url : "uploadUrl/2"
        }
    );
