Hello @liamsaunders,
Thanks for posting in!
Based on the information that you shared, you will need to use the Looper Provider Query String with the following arguments:
$query = array(
'post_type' => 'x-portfolio',
'posts_per_page' => 2,
'offset' => 0,
'ignore_sticky_posts' => true,
'post__not_in' => array( '{{dc:post:id}}' )
);
This argument would give you the following query string: post_type=x-portfolio&posts_per_page=2&offset=0&ignore_sticky_posts=1&post__not_in%5B0%5D={{dc:post:id}}
and this should display the other portfolio items excluding the current portfolio item
Kindly let us know how it goes.
