on ACF (with ACF for Woocommerce installed) when you add a custom field group you have the option to show the fields based on conditions. There is a Woocomerce section which only contains the "checkout" page
My goal is to add a "shipping method" rule under this Woocomerce section which will show the field if shipping_method "My 1st shipping method" is selected
Example show field IF: shipping_method is equal to "My 1st shipping method"
