jQuery UI sortable widget classes option is used to specify the additional classes that need to add to the widget elements. We can use any class that is specified in the theming section which can override their value.
Syntax:
$( ".selector" ).sortable({
classes: {
"ui-sortable": "highlight"
}
});Approach: First, add jQuery UI scripts needed for your project.
<link rel=”stylesheet” href=”//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css”>
<script src=”https://code.jquery.com/jquery-1.12.4.js”></script>
<script src=”https://code.jquery.com/ui/1.12.1/jquery-ui.js”></script>
Example:
HTML
<!DOCTYPE html> <html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet"
