DropzoneADDON DropzoneJS is an open source library that provides drag’n’drop file uploads with image previews

About

Dropzone will find all form elements with the class dropzone, automatically attach itself to it, and upload files dropped into it to the specified action attribute. If you want your file uploads to work even without JavaScript, you can include an element with the class fallback that dropzone will remove if the browser is supported

Panel Title

Dropzone does not handle your file uploads on the server. You have to implement the code to receive and store the file yourself. See the section Server side implementation for more information.

Drop files here or click to upload.
This is just a demo dropzone. Selected files are not actually uploaded.
