Thanks for the code, Adriano.
It didn't quite work for me – instead of producing the respective 'child' (bottom level) posts, it displayed an unlinked bullet list of the 11 most recently published parent posts inside all of the parent posts that have child posts.
Just in case I did something wrong, here are the steps I took in implementing the code:
1. I pasted the entire code in my functions.php (I didn't make any adjustments to the code).
2. I pasted [getchildposts type="countries"] into the countries view template where I want the child/sub-level posts to display inside their respective parent posts.
3. I saved both and checked the countries post types.
Did I take the correct steps?
I wonder whether the code needs tweaking slightly?
Thanks for your continued assistance Adriano, any further help you can provide would be much appreciated.
