Change class of a field label


the default value of a class in a field label is ‘inline’.
How can I change this value through the form setup in the frontmatter.

Thanks in advance.

It seems, that there is no default option to address a label’s class via frontmatter settings - WITHOUT overwriting ‘/user/plugins/form/templates/forms/default/field.html.twig’ by your own version in your theme’s templates.

There is a Twig Varible ‘field.labelclasses’ which can be used for that.
