Functions – Add drop-down search field when searching for Woocommerce orders

I am using the following code to limit the fields in which Woocommerce searches when searching for an order:

/ **
* Limit the search fields of woocommerce orders.
* /
custom_woocommerce_shop_order_search_fields ($ search_fields) {function

// error_log (& # 39; currently searches in these order fields: & # 39 ;. print_r ($ search_fields, true));
unset ($ search_fields);
$ search fields[] = & # 39; _order_key & # 39 ;;
$ search fields[] = & # _Billing_company & # 39 ;;
$ search fields[] = & # 39; _billing_email & # 39 ;;

// error_log (& # 39; now I only look for these order fields: & # 39 ;. print_r ($ search_fields, true));
returns $ search_fields;

}
add_filter (& # 39; woocommerce_shop_order_search_fields & # 39 ;, & # 39; custom_woocommerce_shop_order_search_fields & # 39;);

This limits the search fields to order ID, company and email only, speeding the search for orders. I need to have a drop-down menu along with the search field that will have order ID, Billing company, Billing email as values. If we select order IDs, then the search should only be made in order ID (_order_key), if we select Billing company, then the search should only be made in the field Billing company (_billing_company) and so on. How to add this drop-down menu along with the order search?
