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);
}
