Groups in Filament v4

you can use it with any layout component. For example, you could use a Group component which has no styling associated with it:

public static function configure(Schema $schema): Schema
    {
        return $schema
            ->components([
                    Group::make()
                    ->schema([
                        Section::make()
                            ->schema([
                                TextInput::make('test1'),
                            ])
                    ])->columnSpan(['lg' => 2]),
                Group::make()
                    ->schema([
                        Section::make()
                            ->schema([
                                TextInput::make('test2'),
                            ])
                    ])->columnSpan(['lg' => 1]),
            ])->columns(3);
    }
