Detect if a form has any required fields?

[chrismlusk]

I have a project where we've been directed to add instructions that explain what the asterisks are above each form with a required field.

Is there a way to detect if a form has any required fields at render time? A property or helper so we can add something like:

{% if form.hasRequiredFields %}
    <div>* Indicates a required field</div>
{% endif %}

{{ craft.formie.renderForm(form, renderOptions) }}

There's no property or helper, but looping is the quickest way.

{% set hasRequiredFields = false %}

{% for field in form.getFields() %}
    {% if field.required %}
        {% set hasRequiredFields = true %}
    {% endif %}
{% endfor %}

Thanks for confirming! Looping through the fields will work just fine.
