If your Appearance > Customize > WooCommerce > Product Catalog > Shop page display is set to “Show categories and products“, parent product categories will show in the “products loop” as the very first elements (see screenshot below). They really take up a lot of space and this could be annoying at times, mostly when you don’t use product category images.
Thankfully, if this makes sense to you and your customers, you can remove them easily (it’s one line of code). Also, this works really well when the number of parent product categories is proportional to the number of shop display columns (e.g. you have 6 parent categories and you have 3 products per row under Appearance > Customize > WooCommerce > Product Catalog > Shop page > “Products per row”). Enjoy!
You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
Does this snippet (still) work?
Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.
