How to add an attribute to the first select option in twig symfony form

Question

I need to add a few attributes (f.e. disabled and selected) to the first option in select tag.

this line {{ form_widget(form.idkategoria) }} in twig render:

<select id="foo" name="foo">
<option value="">Kategoria</option>
<option value="1">foo</option>
<option value="2">foo</option>

or how to add an 'attr' to placeholder to keep default 'Kategoria' text.

$builder->add('idkategoria', null, array
                ('placeholder' => 'Kategoria',))

Something like

$builder->add('idkategoria', null, ['attr' => ['placeholder' =>'Kategoria']]) ]

You can find an extract in the official documentation

by saying or how to add an 'attr' to placeholder I meant adding attribute, f.e. disabled or selected, to placeholder which is option tag. Becouse this line ->add('idkategoria', null, array('placeholder' => 'Kategoria','attr'=> array('required'=>true)) makes required a select tag, not option as I wish (Anyway, I walked the problem in completely different way -css-that is not the answer to my question. You can leave this issue. Thanks)
