help adding ‘cart’ to header

Hello @materialmeme,

This is not directly possible without creating child theme.

You can check out documentation on how to create a child theme here: https://developer.www.ads-software.com/themes/advanced-topics/child-themes/

You could override menu-header.php in your child theme: https://github.com/material-components/material-design-for-wordpress/blob/d85870759ec078b426e68f5ea15dd30b41b44959/theme/template-parts/menu-header.php#L61-L64

Let us know how that works out.

Cheers!
