how to put dropzone.js box to existing form in the html?

I am working with laravel. I need put dropzone.js image upload box in to my existing form. normally dropzone comes with form tag and drozone class like this,

<form action="/file-upload"
      class="dropzone"
      id="my-awesome-dropzone"></form>

but I need add dropzone box in to my existing form and save all other data with images using one submit buttons. do you have any idea to configure this?
