The jQuery UI consists of GUI widgets, visual effects, and themes implemented using jQuery, CSS, and HTML. jQuery UI is great for building UI interfaces for the webpages. The jQuery UI Draggable opacity Option is used to set the opacity for the helper while being dragged.
Syntax:
$( ".selector" ).draggable({
opacity: val
});CDN Link: First, add jQuery UI scripts needed for your project.
<link rel=”stylesheet” href=”//code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css”>
<script src=”//code.jquery.com/jquery-1.12.4.js”></script>
<script src=”//code.jquery.com/ui/1.12.1/jquery-ui.js”></script>
Example:

<!doctype html> <html lang="en">
