If you would like to allow your header to be full width for the main container. You can do the following.
Disable store headers under WooCommerce > WC Vendors > Pro > Store headers and then add the following to the themes functions.php
Please Note
This works with any 100% compatible WooCommerce theme. This is any theme that DOES NOT use the optional woocommerce.php file to add WooCommerce support.
If you are using a non compatible theme then please contact your theme developer for how to load this correctly.
The following code is used for the X theme. Do not disable pro headers for this to work.
