Hi @boekel,
Thank you for reaching out.
I understand your concern on how to lower the product list on mobile view and even your menu.
Just for clarity, your theme is responsible for how products are rendered on both desktop and mobile devices, therefore, WooCommerce is not responsible with how they’re displayed on mobile.
I would recommend reaching out to your theme developers for further assistance with this, as it would involve the help of custom CSS code. You can also join our WooCommerce Slack community (it does have a developer channel where you can ask coding questions): https://woo.com/community-slack/
Hope it helps!
