gndesign on "[Plugin: Collapse-O-Matic] Using swaptitle attribute to hide stylized expand button"

Hi there, I am using a stylized div for my expand title, in order to give it the appearance of a button. I would like to use the swaptitle attribute to make the button disappear once it has been clicked, however only the button text is hidden and the background color/div remains. Any suggestions? Thank you!
