->createOptionForm([
    TextInput::make('name')
        ->label('Job Title')
        ->maxLength(255)
        ->required()
        ->validationMessages([
            'required' => 'A job title is required.',
            'max' => 'Job title cannot exceed 255 characters.'
        ]),
    TextInput::make('acronym')
        ->label('Acronym')
        ->nullable()
])
