How can I wrap my input field with a <div> tag when using with Symfony formbuilder?

I am creating an input field with Symfony:

$formBuilder->add($field['fieldName'], TextType::class, array('attr' => array('class' => 'form-control')));

The output is:

<input type="text" id="form_color" name="form[color]" class="form-control">

The output I would need is:

<div class="cp input-group colorpicker-component">
<input type="text" id="form_color" name="form[color]" class="form-control" /> <span class="input-group-addon"><i></i></span>
</div>

This means I somehow have to add a parent to the specific form field. I cannot add it to the actual form, because this parent div is only added to the field in specific cases. Is there a way to do it in the formbuilder?

I'd create my own custom field type to handle these fields.

First define the field class

// src/Form/Type/ColorSelectorType.php
namespace App\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;

class ColorSelectorType extends AbstractType
{
    public function getParent()
    {
        return TextType::class;
    }
}

Then you'll need to create the template for the field:

{# templates/form/fields.html.twig #}
{% block color_selector_widget %}
    {% spaceless %}
       <div class="cp input-group colorpicker-component">
            <input{{ block('widget_container_attributes') }} />
                 <span class="input-group-addon"><i></i></span>
       </div>
    {% endspaceless %}
{% endblock %}

Register your custom templates:

# config/packages/twig.yaml
twig:
    form_themes:
        - 'form/fields.html.twig'

And finally use your new field:

$formBuilder->add($field['fieldName'], ColorSelectorType::class);

Logically, you'll need to customize this to suit your needs, but it should be enough to get you going.
