You can use a plugin or custom code to hide sold out products in WooCommerce. Here are the steps to achieve that:

1. Use a plugin: There are several plugins available that allow you to hide sold out products in WooCommerce. For example, the “WooCommerce Out of Stock Visibility” plugin can help you achieve this. Simply install and activate the plugin, and it will automatically hide sold out products in your product categories.
2. Custom code: If you are comfortable with coding, you can add the following code to your child theme’s functions.php file to hide sold out products:

add_filter( ‘pre_get_posts’, ‘hide_out_of_stock_products’ );
function hide_out_of_stock_products( $query ) {
if ( $query->is_main_query() && ! is_admin() ) {
$meta_query = $query->get( ‘meta_query’ );
$meta_query[] = array(
‘key’ => ‘_stock_status’,
‘value’ => ‘outofstock’,
‘compare’ => ‘=’
);
$query->set( ‘meta_query’, $meta_query );
}
return $query;
}

This code will hide sold out products in your product categories, but the links to these products will still remain active and accessible.
