Woocommerce Remove/Hide Default Sorting Dropdown
This plugin will remove the “Default Sorting” dropdown from shop and archive pages on Woocommerce and Storefront theme. It is ideal for shops which have less than 1 page of (or very few) products. It removes the Default Sorting option by unhooking it, so is a better solution than using CSS. There are no settings, just activate the plugin for it to work.
