I use a cool jQuery plugin called formtips to add inline text to my fields
http://manuelboy.de/projekte/jquery-formtips/
The info clears on focus and is not submitted along with the form. The plugin works by using the "title" of the field, for example:
<input type="text" name="website" value="" id="website" size="40" title="website" />
Right now I'm using the default text/clearit class tip that was mentioned on the forum before. That gets me halfway there, but the default text is still submitted to the form, which is not great.
It would be great if I could somehow add a title to a field so that formtips can use it. Any ideas?
