How do you collapse and expand records without using CFTREE?

I am using Coldfusion and have a webpage that groups summary information by year, like the following:

Year             Number of Stuff                             Avg Time
------            -----------------------                        -----------------
2006
2005
etc..

I want to add functionality that will allow the user to click on the year in order to display detail records for that year on the page.  I need a control/tag that allows the user to expand and/or collapse detail records.  I do not want to use the CFTREE tag.

Thanks!
