Category List changed into type and filter

Question

I am not sure if this is a woocommerce or a wordpress behaviour (I can't find anything about this). But it seems when the number of product categories become a lot, the backend admin dropdown changes into a type and filter box. I'd like to keep this as a dropdown menu. Is there any information, hook about this?

Answer 1

It is a WooCommerce behaviour and can be modified with this filter woocommerce_product_category_filter_threshold which defaults to 100.

You can use it like so

add_filter('woocommerce_product_category_filter_threshold', 'return500');

function return500(){
    return 500;
}

The following also works for unlimited

add_filter('woocommerce_product_category_filter_threshold', '__return_true');
