Single File Upload

Dropzone requires a valid server-side url for the file upload. You can easily pass it through data-options attribute like data-options!={ url: 'valid/url'}

<div class="dropzone dropzone-multiple p-0 mb-5" id="my-awesome-dropzone" data-dropzone="data-dropzone" data-options='{"url":"valid/url","maxFiles":1,"dictDefaultMessage":"Choose or Drop a file here"}'>
  <div class="fallback"><input type="file" name="file" /></div>
  <div class="dz-preview dz-preview-single">
    <div class="dz-preview-cover dz-complete"><img class="dz-preview-img" src="../../../assets/img/generic/image-file-2.png" alt="..." data-dz-thumbnail="" /><a class="dz-remove text-danger" href="#!" data-dz-remove="data-dz-remove"><span class="fas fa-times"></span></a>
      <div class="dz-progress"><span class="dz-upload" data-dz-uploadprogress=""></span></div>
      <div class="dz-errormessage m-1"><span data-dz-errormessage="data-dz-errormessage"></span></div>
    </div>
    <div class="dz-progress"><span class="dz-upload" data-dz-uploadprogress=""></span></div>
