How to hide form fields in twig template?

I have a Symfony form that includes two TextType fields. If a certain check evaluates to false, I don't want to display the input fields but output the static content of the field and include the form fields as hidden fields instead. How can I do that?

If you use Symfony 4.4, you can set the `div style="display: none;" style:

{{ form_start(form) }}
  <div class="row">
    {% if app.user %}
    <div class="col-lg-12">
      <fieldset>
        Login by: {{ app.user.username }}
      </fieldset>
    </div>
    <div class="col-lg-12">
      <fieldset>
        Mail : {{ app.user.email }}
      </fieldset>
    </div>
    <div class="col-md-12 col-sm-12" style="display: none;">
      <fieldset>
        {{ form_widget(form.owner, { 'attr': {'class': '', value: 'null'}}) }}
      </fieldset>
    </div>
    {% else %}
    <div class="col-md-6 col-sm-12">
      <fieldset>
        {{ form_widget(form.owner, {'attr': {'class': ''}}) }}
      </fieldset>
    </div>
    {% endif %}
    <div class="col-lg-12">
      <fieldset>
        {{ form_widget(form.content, {'attr': {'class': ''}}) }}
      </fieldset>
    </div>
    <div class="col-lg-12">
      <fieldset>
        <button type="submit" class="main-button">New</button>
      </fieldset>
    </div>
  </div>
{{ form_end(form) }}

You can prevent any output for the form field by pretending, that it was already rendered:

{{ form_start(form) }}
    {% if someValue == true %}
        {% do form.fieldName.setRendered() %}
    {% endif %}
{{ form_end(form) }}

you can use HiddenType, or hide field in template:

{{ form_start(form) }}
    {% if someValue == true %}
        {{ form_widget(form.fieldName) }}
    {% else %}
        {{ form_widget(form.fieldName, { 'attr': {'class': 'hidden-row'} }) }}
    {% endif %}
    {# other fields... #}
{{ form_end(form) }}

or you can use FormEvents like FormEvents::PRE_SET_DATA in FormType. (doc)
