How easy is it to write a custom form.as_ function?

I’m hoping this already exists, but I can’t find it. I’m trying to render forms in the bootstrap 5 paradigm; i.e.

{% for field in form.visible_fields %}
<div class="row">
  {{ field }}
</div>
{% endfor %}

…so I’d like to write a form.as_row function so I don’t have to do this manually in each template. I’m assuming this is going to involve subclassing BaseForm, has anyone got an example of this? Or, better still, a plugin that already does this.

Thanks!

I think there’s some potentially-useful context missing here from what you’re trying to ask. It might be helpful if you described what the ultimate desired outcome is.
