Conditional layouts for WooCommerce product archives based on parent category

In the members-only forum, a user asked:

I’m trying to show or hide the sidebar using the full-width-content or sidebar-content layout on categories depending on the parent category in WooCommerce.

I have a lot of sub categories so don’t want to do it manually in the archive setting of each category.

I also need to do adjustments for the single products depending on the parent category adding and removing some elements.

In a function hooked to genesis_pre_get_option_site_layout we can check if the current page is a product category archive and if so, get the current term object and if this term has a specific parent, return full-width-content (or any other) Genesis layout.

Coming to the second part of the question, in a function hooked to our desired WooCommerce single product location say, woocommerce_single_product_summary, we can get the terms of the product, loop through each of them and check the term's ID against a specific parent term's ID and if they match, show some special text - as an example of customization to add an element.

Add the following in child theme's functions.php:
