PHP FILAMENT attaching to a model with related table

I’d like to customize the attach select that is shown when i attach a resource to a course.

The model to attach to has a relation to a related table (like a category of the resource).

Table COURSE

Table COURSE_RESOURCE
course_id
resource_id

Table RESOURCE
resource_name
resource_type_id
….

Table RESOURCE_TYPE
resource_type

When attaching a resource to a course with the relationManager, i’d like to be able to use the select to filter on both the resource_name AND the resource_type. Or at least showing the resource_type with the resource_name and not only the resource_name.

The issue is that i have multiple same resource_name that have different resource_type. Right now, i could search by resource_name and their are all showed but i can tell wich select option is related to which resource_type.

I try this (where resourceType is the eloquent model relation belongsTo between the 2 tables resource && resource_type)

AttachAction::make()
->recordSelectSearchColumns([‘resource_name’, ‘resourceType.resource_type’])

but i doesn’t work, it does not make the join in the query.

An other way would be to present a full table of the model to attach to instead of just the select.

Is there a way to setup the attach form to show a full table of resource (with related resource_type column) with filter so that you can select any row to attach to (after eventualy filtering) ?

Any idea ?
