Positioning the field description and warnings/errors between label and input field is considered bast practice for accessibility of forms. https://nldesignsystem.nl/richtlijnen/formulieren/descriptions/plaatsing https://nldesignsystem.nl/richtlijnen/formulieren/foutmeldingen/plaatsing

Currently Open Forms positions these messages under the input fields.

As a form builder i would like to be able to set the position to adhere to these best practices. While at the same time allow me to use the current solution for certain situations that require it.
