Your documented filter relationship_ajax_data exists and its working perfect! But like i do it with the select2 fields to “change” my result, i want to do the same with the relationship field. But the _result doesnt exist and therefore i asked for a solution.
My target is to “disable” options in one relationship field if this item is selected in another. Bases on the query i couldnt do this easy with HTML and it would be better to modify the result coming via AJAX.
