I want to setup a 'Pages' channel in such a way where I can include a loop from a different channel (in this case 'Listings') only showing entries for a particular category. I'm using Structure to arrange my sitemap, so I can't use segments in the URL - plus it will only be relevant for certain pages and not others, so I need to find a way the user can select a related 'Listings' category when editing the 'Page' if appropriate which would then power a listings loop.
Can anyone advise or link to somewhere that shows how to do this?
Thanks, Justin
