Form::make()
    ->schema([
        TextInput::make('name')->required(),
        TextInput::make('email')->email(),
    ]);
```

## Validation

```

    ->rules(['max:255']);
```

### How do I add custom validation?

        fn ($attribute, $value, $fail) =>

                ? $fail('No spaces allowed')
                : null,

    ->options(fn ($get) =>
        State::where('country_id', $get('country_id'))
            ->pluck('name', 'id')
    );
```

### How do I show/hide fields conditionally?
