Enable the dropdown mobile layout for all style

With version 2.0 of Multistep Checkout we have introduced the new style for mobile viewing. If you want to enable the dropdown style also for the old styles (text, style 1, style 2 and style 3) you can do it with this PHP code by inserting it inside the functions.php of your theme:

add_filter( 'yith_wcmv_have_mobile_timeline', '__return_true' );
