[pmwiki-users] Listing pages by their category

[Simon]

I would like to list a group of pages (e.g. cooking recipes) by their
categories.

This turned out to be harder that I thought it would be.

My approach needs a nested pagelist,

You can see the approach here
http://www.pmwiki.org/wiki/Test/PagelistByCategory

The major issue is that I can't hide the category section headings if there
are no pages from the group in that category, as far as I can see, with
nesting a further pagelist.
It seems to be access the a variable which returns the number of pages for
a set of pagelist parameters would be useful, e.g along the lines of the
syntactically incorrect
(:if equal (:pagelist link=x/y fmt=count:) 0:)

I'd welcome any suggestions on this

thanks

Simon
