How do I set up the variable information in a free format question to capture date from a date picker, such as the one from JQuery (see below).
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>datepicker demo</title>
<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>
</head>
<body>
<div id="datepicker"></div>
<script>
$( "#datepicker" ).datepicker();
</script>
</body>
</html>
