bulma (input/field): `field` macro now has `control_class` and `in_group` attributes: - `control_class` is used to specify additional classes for the control (when `class` is used for classes of the of the `field`) - when `in_group` is `true`, `field` is not added, only the `control` is used. This is useful for grouping elements in the same field

{% macro form(action='', class='') %}
<form method="post" action="{{action}}" {{ {'class': class}|xmlattr }} {{kwargs|xmlattr}} >
    {% if csrf_token is defined %}
        <input type="hidden" name="csrf_token" value="{{csrf_token}}">
    {% endif %}
    {{ caller() }}
</form>
{% endmacro %}
