can also contain an "extra_info" key which will add some help text after the
input element.

form_info     - A list of dicts describing the form field to build.
data          - The form data object.
errors        - The form errors object.
error_summary - A list of errors to display above the fields.

Example

  {% set form_info = [
      {'name': 'ckan.site_title', 'control': 'input', 'label': _('Site Title'), 'placeholder': ''},
      {'name': 'ckan.main_css', 'control': 'select', 'options': styles, 'label': _('Style'), 'placeholder': ''},
