How to add the first default value in a dropdownlist? I tried to do this:
{!! Form::select('Usuario.est_id',array('null' => 'Selecione') + $estados, null, ['class' => 'form-control']) !!}
but I get the error: FatalErrorException in 30aae33d562adffd11ade38d9100e329 line 26: Unsupported operand types
The $ states are a collection.
