KERN UX Form Theme for Symfony
==============================

[](#kern-ux-form-theme-for-symfony)

A Symfony form theme that renders forms with the markup of [KERN UX](https://www.kern-ux.de/komponenten/), the open design system for German public administration — analogous to Symfony's built-in `bootstrap_5_layout.html.twig`.

The theme covers the KERN form components: text inputs, textareas, selects, radio/checkbox groups (as `kern-fieldset`), single checkboxes, buttons, hints, and error messages (inline `kern-error` per field, `kern-alert` on the root form). Following the KERN guidelines it marks *optional* fields instead of required ones and uses `aria-required` rather than the native `required`attribute.

> **Note:** This package ships markup only. Your application must include the KERN UX styles itself, e.g. via [`@kern-ux/native`](https://www.npmjs.com/package/@kern-ux/native).

Requirements
------------

[](#requirements)

- PHP 8.1+ (PHP 8.4+ for Symfony 8)
- Symfony 6.4, 7.x or 8.x (`symfony/form` + `symfony/twig-bridge`)

Installation
------------

[](#installation)

```
composer require inixmedia/kern-ux-form-theme
```

If you don't use Symfony Flex, register the bundle manually:

```
// config/bundles.php
return [
    // ...
    Inixmedia\KernUxFormTheme\KernUxFormThemeBundle::class => ['all' => true],
];
```

Usage
-----

[](#usage)

Enable the theme globally:

```
# config/packages/twig.yaml
twig:
    form_themes:
        - '@KernUxFormTheme/kern_layout.html.twig'
```

Or per template:

```
{% form_theme form '@KernUxFormTheme/kern_layout.html.twig' %}

{{ form(form) }}
```

Rendered markup
---------------

[](#rendered-markup)

A simple text field row renders as:

```

    Vorname
    Wie im Ausweis angegeben

```

Expanded choices become a KERN fieldset:

```

    Anrede

            Frau

        ...

```

Development
-----------

[](#development)

```
composer install

# Run the test suite (renders real forms through the theme)
composer test

# Lint the Twig templates
composer lint
```

License

KERN UX itself is developed by the German federal and state governments; see [kern-ux.de](https://www.kern-ux.de/) for the design system's own licensing.
