Filtering a Select field's options based on a parent relationship
I'm creating a form where I can create a new instance of a
CompletedTrainingQualification
CompletedTrainingQualification
, which uses a BelongsTo
TrainingQualification
TrainingQualification
relationship, which in turn BelongsTo a
TrainingProvider
TrainingProvider
. My issue is that I would like to have a form that utilises a select box to select a provider, and then the value of training_qualification_id can be selected in a seperate select box (using the normal select relationship field in filament), where the options are only those which have a training_provider_id of the one selected. I am open to achieving this is a different way too, but the main point is being able to select a qualification based off of the provider, where the provider is not stored on the CompletedTrainingQualification record when the form is submitted. Grateful for any help, cheers.
