One big "Concertina" page - nearly working . .

People,

I have managed to get started with:


and it is _almost_ doing what I want - which is: when someone expands one section, I would like any other expanded section(s) to be collapsed, so the total page length is always minimised.  I guess this must be possible but I have no clue about how to start modifying the code to get it to do this . .

Pointers to code where this behaviour is already available or how to get it done are appreciated!

Regards,

Phil.
