$cities = collect([1 => 'Gotham City', 2 => 'Springfield'])
{!!Form::select('city', 'Choose your city')->options($cities)!!}

// With model collection
$cities = \App\City::all();
{!!Form::select('city', 'Choose your city')->options($cities)!!}

// Your model should have id and name attributes. If these keys are different,
// you can pass second and/or third parameters (you can use the second parameter to access some model acessor, also)
$cities = \App\City::all();
{!!Form::select('city', 'Choose your city')->options($cities, 'city_name', 'id_object_field')!!}

// When you are using collections, you can use prepend method
// (https://laravel.com/docs/5.8/collections#method-prepend) to add an first empty value, like "Choose your city"
$cities = \App\City::all();
{!!Form::select('city', 'Choose your city')->options($cities->prepend('Choose your city', ''))!!}
