    Hi, i have a relationship from pictures to books. the relationship is 1:1 Reciprocal relationship. i want to prevent assigning a pictures post (type). to a different book. I basically want to hide the already linked relation post so it not get reassigned to different.

    i see there is Query args, wonder if anyway we can exclude those already have relationship assigned.

    Thanks.

    Hello,

    Thanks for reaching out.

    There isn't an option to exclude a post from the list if it has a relationship. I will inform the development team to consider supporting this feature in future updates.

    Regarding the reciprocal, it will work if you have the relationship for the same post type. Like from pictures to pictures. Following the documentation https://docs.metabox.io/extensions/mb-relationships/#relationship-settings

    Hello,

    That code using has_one_relationship is correct. You can refer to the documentation https://docs.metabox.io/extensions/mb-relationships/#using-code

    In the builder, you can enable the option "Has one relationship" when editing/creating the relationship. Please check this screenshot https://ibb.co/CKj5nDb6

    Thanks.
