updating cfdiv onclick

Greetings all. I see in the docs how to bind cfdiv to a form field, but how
does one interact/update the div on click? or possibly cfdiv isn't what I
want at all.

basically, i have an area that, onload, i want to be invisible. clicking on
any number of links in the page will open that area and that area will
refresh itself with content from a URL, depending on the value that the link
sets. so lets say you click on link1, and it that link has a param of
?att=1, and so the div sees that attribute and fetches mypage.cfm?att={att}
or some such thing.

what's the preferred way of getting this functionality in CF8?

thanks a lot.

Marc
