You first have to define add dropzone in form:

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js">
  </script>`
 <script src="../../assets/dropzone/js/dropzone.js"></script>
 <link type="text/css" rel="stylesheet"
         href="../../assets/dropzone/css/dropzone.css">

  <div action="" id="dZUpload" class="dropzone" method="post" 
     enctype="multipart/form-data">
  <div class="dz-default dz-message">Drop files here to upload or click</div>
 </div>

after that add js for dropzone:

  <scirpt>
  $(document).ready(function () {
    Dropzone.autoDiscover = false;
    var url = "http://locahost/url/createpage";

    console.log(url);
    $('#dZUpload').dropzone({

        url: url,
        addRemoveLinks: true,
        maxFiles: 5,
        autoProcessQueue: false,
        enqueueForUpload: false,
        uploadMultiple: true,
        autoDiscover: false,
        parallelUploads: 5,
        clickable: true,
        maxFilesize: 100,
        acceptedFiles: "image/jpeg,image/png",

        success: function (file, response) {
            var imgName = response;
            file.previewElement.classList.add("dz-success");
            console.log("Successfully uploaded :" + imgName);
        },

        init: function () {

            var myDropzone = this;

            myDropzone.on("addedfile", function (file) {
              alert("new file added");
            });

            myDropzone.on("maxfilesexceeded", function (file) {
                this.removeFile(file);
            });

            var submitButton = document.querySelector("#submit");

            submitButton.addEventListener("click", function (file) {

                if (myDropzone.getQueuedFiles().length > 0) {

                    var submitfiles = false;

                    if (submitfiles === true) {
                        submitfiles = false;
                        return;
                    }

                    file.preventDefault();

                    var deleted_image_data = document.getElementById('deleteImage').value;
                    myDropzone.on('sending', function (file, xhr, formData) {
                        formData.append('deleted_image_data', deleted_image_data);
                    });

                    myDropzone.processQueue();

                    myDropzone.on("complete", function () {
                        submitfiles = true;
                        $('#submit').trigger('click');
                    });

                }
            });
        }
    });
});</script>
