Laravel Form::select shows nothing

Hi I'm using Laravel version 5.6 and got a problem in view with Form::select.

I already made some Form::open with 'text' and 'textarea' they all worked fine, but the Form::select do not generate the select fild on my view.

I used this code:

{!! Form::label('isPropaganda', 'Propaganda:') !!} {!! Form::select('isPropaganda', ['Não' => '0', 'Sim' => '1'], null, ['class'=>'form-control','multiple']) !!}

I found the example here http://laravel-recipes.com/recipes/163/creating-a-select-box-field but didn't workout. How can I fix it?
