How do you use form themes in Symfony?

Answer: In Symfony, form themes are used to customize the rendering of forms. You can use form themes by creating a Twig template that extends the default form theme, then specify this custom theme in your form rendering. To use a form theme, follow these steps:

1. Create a Twig Template: Define a Twig file (e.g., `form_theme.html.twig`) with your custom markup.

2. Include the Theme: In your controller or Twig template, include the custom theme with:
“`twig
{% form_theme form ‘form_theme.html.twig’ %}
“`

3. Render the Form: Render the form as usual, and it will apply your custom styles and structure.

This allows for tailored form rendering while keeping your application maintainable.
