Collapse content plugin

Hi there team!

During the creation of a Landingpage I was wondering te following. The page is becoming pretty long so is there a way to collapse content?

I searched for plugins and found a few but have know Idea if they work on a WP Multisite.

For example: http://wordpress.org/plugins/jquery-collapse-o-matic/screenshots/

Do you guys know any that works?

Thanks in advance!
