also how can i hide the price from the cart in the menu

Please add below CSS code to WP-Admin → Appearance → Customize → Additional CSS:

.woofc-menu-item .woofc-menu-item-inner-subtotal {
    display: none;
}

His first question was not answered. Is there a shortcode or HTML snippet we can paste to show the WPC Fly Cart in a specific location?
