This is a basic tooltip nav menu. By setting each list item to a class of "listitm" we can target each internal link and use the title attribute for extra text! It's all fairly simple to implement within your own website and provides a wonderful UI effect for your visitors. Also each small tooltip will act as an extension of the link, so visitors are able to click either and still visit your page.
Another great thing to note is our script will degrade gracefully with JavaScript turned off. Instead regular tooltips will be displayed, no errors for IE or older versions of browsers. We're using the jQuery colortips library to save some time. These are packaged within the demo download!
