Is it possible?

Hi Meirk,

Thanks for asking! I'd be happy to help.

To filter out specific posts which have a relationship with another post, you have a couple of options:

1. If you're showing your posts through a view, you can create a custom shortcode that gets the ID of the post and checks it for a relationship using "toolset_get_related_posts" ( https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_posts ).

If a relationship is found the shortcode can return 'true" and if not it can return "false".

Next, you can use this shortcode in a condition to show or hide content from that specific post:

2. Another option is to use a secondary view to generate a list of IDs for all those posts which are in a relationship and then use those IDs in "post__not_in" array to be excluded from your primary view's output.

I hope these suggestions will help.
