David Leedy Is Reading My Mind !

I was contemplating some xpages development and wanted to work through duplicating some UI functionality that I use in a traditional Notes desktop application. The problem relates to collapsing or expanding a categorised view from a button. I had spent a little time working out what I wanted but it didn’t seem to be working as expected. How surprised was I when I spotted an article and video by David on the exact problem I was working on.

Heres the link for the video.
