When making a dynamic relation filters, it can only use to-one relations as references and not to-many (contains any of). This is a limitation. Use case: show all other contacts in the company when logging a call. A call can be with multiple people. Maybe from different companies. If I select one person from company x, it should then show me all other people in company x. If I then press someone on company y, it should show everyone in company x and everyone in company y. ---

I think this is related as well: [In embedded Views, allow Filtering on Relation fields for "Is this entity"](https://community.fibery.io/t/in-embedded-views-allow-filtering-on-relation-fields-for-is-this-entity/3635) ---

I don’t think so. But maybe the request is unclear then. Here’s what I mean: This works. Contacts is many to many, Company is many to one. ![Screenshot 2025-05-22 at 16.55.50](https://us1.discourse-cdn.com/flex020/uploads/fibery/original/2X/5/5af8eef36c31b0a80be574b0d485efd708986cf2.jpeg) When you change the company to “to-many”: ![Screenshot 2025-05-22 at 16.55.58](https://us1.discourse-cdn.com/flex020/uploads/fibery/original/2X/7/7e134e017a242de441706f4658f50f848f47ba09.jpeg) Dynamic filtering no longer works. ![Screenshot 2025-05-22 at 16.56.43](https://us1.discourse-cdn.com/flex020/uploads/fibery/original/2X/7/7a2de1336e343151e302aa30982467fc1edbd482.jpeg) ---

You’re not wrong, they are different enough (yours is about the relation/link UI and the other is about the filtering UI) but they’re both related to gaps in dynamic/context filtering so I wanted to make sure they were generally linked. I think context filtering is currently half-baked and needs major expansion/improvement. ---

I see, makes sense! Agreed that context it’s such big selling point of Fibery, yet the way it works right now results in a subpar experience in different areas. (Just the fact that is works in such different ways in different places) ---

I just ran into this issue. And I realize this is actually pretty critical for building out data hierarchy across 3 or more databases. With context filtering you can essentially nest databases within each other such that records are only available if the parent database is the same between child databases. Database A (Parent of B & C - One to Many) Database B (Child of A - Many to One) (Many to Many Relationship with C) Database C (Child of A - Many to One) (Many to Many Relationship with B) When linking records of B and C together only the records that are linked to the Parent Database A should be available. To do this we need a dynamic filter on the Many to Many Field Views so that only those items appear.
