                {% set form = active_form_begin({
                    'id': 'contact-form',
                    'action' : '',
                    'options': {
                    }
                }) %}
            
                    {% set script %}
            JSONEditor.defaults.language = "de";

              error_notset: "Muss gesetzt sein",
              error_notempty: "Pflichtfeld"
            };
            {% endset %}
            {{ this.registerJs(script) }}
                    {{ form.errorSummary(model) | raw }}
                    {{ this.registerJs('JSONEditor.plugins.selectize.enable = true;') }}
                
        
                {{ json_editor_widget_widget(
                    {
                        'model': model,
                        'attribute': 'json',
                        'options': {
                            'id': 'contact-json'
                        },
                        'clientOptions': {

                            'no_additional_properties': true,
                            'show_errors': 'always'

                    }
                ) }}   
            
                {{ Html.submitButton('Senden', {
                    'class': 'btn btn-primary btn-default',
                }) | raw }}
                       
        
                
            {{ active_form_end() }}

How to add a date picker

If you like to add a all browser working date picker you need a script in the twig and some extra css.

Code for Twig

{# documentation: https://jqueryui.com/datepicker/ #} 
{# styles are in less/form.less #} 

{% set datePickerScript %}
    $.ajax({
      url: 'https://code.jquery.com/ui/1.12.1/jquery-ui.js',
      dataType: "script",
      success: function () {
        $('[name="root[Datum]"]').datepicker({
            dateFormat: "dd-mm-yy",
            constrainInput: false
        });
      }
    });
{% endset %}
{{ this.registerJs(datePickerScript) }}

CSS for Less ` .ui-datepicker {

background: #fff;
