{#
    This field relies on the `text.html.twig` implementation.

    Mautic tries to render `@themes/{{theme}}/html/MauticFormBundle/Field/text.html.twig`
    and falls back to the standard template '@MauticForm/Field/text.html.twig'.

    This eliminates the need to copy twig templates into themes that just rely on one base template file.
