Hi Aldhi,

In order to use Toastr notifications you need to include this library:

<script src="assets/js/toastr.js"></script>

Then to show it in the page, you can use this way:

toastr.success( 'Your message here...', opts );

An example of that is here:

<script type="text/javascript">
	jQuery(document).ready(function($)
	{
		// Sample Toastr Notification
		setTimeout(function()
		{
			var opts = {
				"closeButton"       : true,
				"debug"             : false,
				"positionClass"     : "toast-top-right",
				"toastClass"        : "black",
				"onclick"           : null,
				"showDuration"      : "300",
				"hideDuration"      : "1000",
				"timeOut"           : "5000",
				"extendedTimeOut"   : "1000",
				"showEasing"        : "swing",
				"hideEasing"        : "linear",
				"showMethod"        : "fadeIn",
				"hideMethod"        : "fadeOut"
			};
	
			toastr.success("You have been awarded with 1 year free subscription. Enjoy it!", "Account Subcription Updated", opts);
		}, 3000);
	});
</script>
