title: Integrating Dropzone.js into existing HTML form with other fields
body: <p>I currently have a HTML form which users fill in details of an advert they wish to post. I now want to be able to add a <em>dropzone</em> for uploading images of the item for sale.</p>
  
  <p>I have found <a href="https://www.dropzonejs.com/" rel="noreferrer">Dropzone.js</a> which seems to do most of what I need. However, when looking into the documentation, it appears that you need to specify the class of the whole form as <code>dropzone</code> (as opposed to just the <em>input</em> element). This then means that my entire form becomes the <em>dropzone</em>.</p>
  
  <p>Is it possible to use the dropzone in just part of my form, i.e. by only <strong>specifying the element as class <em>"dropzone"</em></strong>, rather than the whole form?</p>
  
  <p>I could use separate forms, but I want the user to be able to submit it all with one button.</p>
  
  <p>Alternatively, is there another library that can do this?</p>
  
  <p>Many thanks</p>
