I solved this 5min after posting it…
<?php $form_id = get_field('event_registration_form_id'); ?>
<?php gravity_form( $form_id , false, false, false, '', true, 12 ); ?>
Not sure that is the cleanest or ‘proper’ way but it works 🙂 If there is a better way to do it, let me know. Again, php noob here.
