Is there a way to get in the widget area a woocommerce product filter that would filter products according to some of the ACF fields values ?
Thank you in advance for your suggestions.
I’m afraid you need to create a separated filter rather that integrating it in WooCommerce filter. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/creating-wp-archive-custom-field-filter/.
Hope this helps!
