Grouping by parent in a Select component

I have a 3 models - Brief, CustomOption and CustomOptionType. Each Brief belongs to many CustomOptionType with a pivot table -

    public function customOptionTypes(): BelongsToMany
    {
        return $this->belongsToMany(CustomOptionType::class, 'brief_custom_option_types', 'brief_id', 'custom_option_type_id')
            ->withTimestamps();
    }

    public function customOptionTypes(): BelongsToMany
    {
        return $this->belongsToMany(CustomOptionType::class, 'brief_custom_option_types', 'brief_id', 'custom_option_type_id')
            ->withTimestamps();
    }

And each CustomOptionType belongs to CustomOption -

  public function customOption(): BelongsTo
  {
      return $this->belongsTo(CustomOption::class);
  }

  public function customOption(): BelongsTo
  {
      return $this->belongsTo(CustomOption::class);
  }

Now, in BriefResource.php - I'd like to group this Select component by the 'parents' of the custom option types -

 Select::make('Custom Options')
                        ->label('Custom Options')
                        ->preload()
                        ->searchable()
                        ->relationship('customOptionTypes', 'name')
                        ->multiple(),

 Select::make('Custom Options')
                        ->label('Custom Options')
                        ->preload()
                        ->searchable()
                        ->relationship('customOptionTypes', 'name')
                        ->multiple(),

I know you can group them when explicitly using the ->options() function, but in this case im loading those directly via a relationship so im not sure how to achieve that. Thanks in advance.

you will need to override the options() etc to group them

yes, but in my case the options are being loaded automatically due to the ->relationship() function

i would guess you should generate options manually in this case
