The following displays the imFeedBack JQuery UI Widget displayed on the right. Select themes from the ThemeSwitcher below to view the different color schemes. I'm using the ThemeSwitcher for this example, but you can create a customized theme on JQueryui.com.
The imFeedBack widget has a few configuration options that can be used when styling the widget. The only mandatory option is the submission url.
$(document).ready(function(){
$(document.body).imFeedBack({
submit_url: 'http://www.mysite.com/send_mail.php'
});
});
