Sometimes you just need a simple fix. It may be something you do with a bit of coding, or perhaps a simple plugin is the right option. Such is the case with the sorting options on your WooCommerce shop page.
Toggle Sorting Options Off and On
As I mentioned, a simple fix. The WooCommerce Remove Product Sorting plugin is a free plugin from my friends over at Skyverge.
After installation, you will find the options to for the plugin in your customizer. Once there, just click on WooCommerce > Product Catalog and you will see where you can toggle off as many of the default sorting options that you want.
As you can see here, it works like a charm.
Adding Sorting Options
There is another free plugin that gives you the ability to add extra sorting options to your WooCommerce product page for alphabetical, sales, in-stock and reviews as well as changing the default sorting label. You can see that post here.
