dropzone is a jQuery plugin used to create a highly customizable drag'n'drop zone for file uploading with a progress bar. Your user can drag and drop a file onto it, and the file gets uploaded to the server via AJAX. Based on Bootstrap styles.

How to use it:

1. Include the needed jQuery library and Bootstrap framework on the webpage.

<link rel="stylesheet" href="bootstrap.min.css">
<script src="//code.jquery.com/jquery.min.js"></script>
<script src="bootstrap.min.js"></script>

2. Create a container to place the file upload zone.

<div class="dropzone"></div>

3. Active the plugin and specify the file or url you wish to post the files.

$(".dropzone").dropzone({
  url: 'upload.php'
})

4. All customization options with default values.

// width of the div
width:                  300,
