Issue: MorphToSelect with Translated Titles

I'm struggling to set up a MorphToSelect field for a polymorphic relationship where I need to display translated titles.

Here's my current setup:
MorphToSelect::make('productable')
    ->types([
        MorphToSelect\Type::make(Course::class)
            ->titleAttribute('id') <-- Here I want to display a column from the related table, I want to display the course_title in the primary language.
            ->getOptionLabelUsing(function (Course $record): string {
                return $record->translations()
                    ->where('locale_id', $record->primary_locale_id)
                    ->first()?->course_title ?? 'Untitled Course';
            })
            ->getSearchResultsUsing(function (string $search): Builder {
                return Course::whereHas('translations', function ($query) use ($search) {
                    $query->where('course_title', 'like', "%{$search}%");
                });
            }),
    ])
    ->native(false)
    ->required(),

Courses have translations in a separate table.

I can't get the translated title to display in the select field - I either get errors about undefined columns or the ID is displayed instead of the title.

How can I properly set this up to:
  • Display the course title in the primary language.
  • Allow searching based on translated titles.
  • Correctly save the polymorphic relationship.
Any help is appreciated!
