This filter allows you to add additional classes to the various html entities ( i.e. form labels, container, select drop down, etc.). It takes 3 parameters:

  • 'yes' or 'no' string for Autoship product
  • WooCommerce product number 
  • A boolean weather product has discount


// add dashed border and change the dropdown to black & white using CSS classes
function new_skin($select_skin_arr){
    $select_skin_arr['container'] .= ' transparant_container';
    $select_skin_arr['select'] .= ' negative';
    return $select_skin_arr;
add_filter('autoship_product_schedule_options_select_skin', 'new_skin', 10, 1);
