Hi Torsten

Thank you so much for your reply. I've tried adding it to a page with 9 
subpages and it limits the subpages to 3 fine, but doesn't seem to want to 
add the pagination. I'm sure I'm doing something simple wrong so let me 
explain.

I've added the code you provided to the setup of an ext template in the page 
where I want this funcitonality. I then added a standard Menu of subpages 
content element. I noticed in the source code of the generated page that it 
didn't wrap the menu in the csc-menu-1 div tags.

The page I've added it on is http://www.intersites.co.uk/11333/ Underneath 
I've added a standard Menu of sybpages with abstract (which uses the same 
look and feel) so you can see the difference in the page source.

I'm sure I've done something silly like adding it all to an extension 
template when I shouldn't have or something like that, so any advice would 
be very greatfully received.

Thanks again for the detailed reply and sorry to bug you with more 
questions.

Kind Regards

Dave
