JQuery is part of Drupal core and provides a library for doing this:
http://jquery.com/.

You'll need to write a bit of JavaScript specific to your application.

The best getting started text I've seen to date is in the Pro Drupal
Developers book, though it's still bare essentials. Doing a quick
Google (because you made me curious :-) the best I found in 30 seconds
was this:
- http://del.icio.us/kentbye/jquery
- http://www.slideshare.net/robknight/beginning-jquery-in-drupal-theming/

In a nutshell, the JQuery library is already there. You need to
include your JavaScript code for collapse/uncollapse on the target
page. There are a variety of methods for doing this, the best one
depends on the specific situation (eg: site wide, per page).
