I only want to add a class to the inside the fieldset from fieldset.html.twig. It's a bit overkill to extend the template for just to add a class.

How can I achieve this with a preprocess function?

function mytheme_preprocess_fieldset(&$variables) {
// $variables['children']['attributes']['class'][] = 'mb-4';
}
  • Did you check the content of $variables['children']? It might be already rendered, in which case you are too late and need to find the preprocess hook of the template containing the div which was rendered earlier. – 4k4 Jun 5 at 14:40

Under a fieldsets 'Advanced' settings tab, you can add custom attributes to the fieldset.
