I'm working on laravel 5.5

I have these lists:

{!! Form::mySelect('id_uso', 
                   'Uso', 
                   [0 => 'Escoge una opción'] + App\Usos::pluck('nombre', 'id')->toArray(), 
                   null, 
                   ['required','id' => 'listaUsos', 'class'=>'chosen']) !!}

{!! Form::mySelect('id_padre', 
                   'Servidor padre: Escojer unicamente los que esten marcador con - 1', [0 => 'Escoge una opción'] +
                   App\Servidores::select(DB::raw("CONCAT(hostname, ' - ', id_uso) AS hostname_version"), "id")-> pluck('hostname_version', 'id')->toArray(),       
                   null, 
                   ['required','class'=>'requerido-con-virtual', 'style' => 'width: 100%;']) !!}

The problem is that when saving, take this value [0 = > 'Choose an option'], and I need you to be required to choose a value from the list, instead of taking 'Choose an option', I put the required, but it does not work.

Could someone help me?

Thanks for reading, happy day.

You could have your validation, within your FormRequest or where you validate the data. apart from the rule required the rule not_in:0 to avoid the first element of select

'id_padre' =>'required|not_in:0',
'id_uso' =>'required|not_in:0'

Another colleague from the community helped me solve the problem in a comment on another question.

To this drop-down list:

{!! Form::mySelect('id_padre', 
                   'Servidor padre: Escojer unicamente los que esten marcador con - 1', [0 => 'Escoge una opción'] +
                   App\Servidores::select(DB::raw("CONCAT(hostname, ' - ', id_uso) AS hostname_version"), "id")-> pluck('hostname_version', 'id')->toArray(),       
                   null, 
                   ['required','class'=>'requerido-con-virtual', 'style' => 'width: 100%;']) !!}

I removed this part so that I would not take it as a first option:

[0 => 'Escoge una opción'] +

Y Le adicione

['required','class'=>'requerido-con-virtual', 'style' => 'width: 100%;', 'placeholder' => 'Escoge una opción']) !!} <-----

For me to take the required, and the placeholder to send the message that I should choose an object from the list, without that text being taken as a value.

I thank everyone for your attention, Thank you very much.
