The Oxygen Builder Menu Cart for WooCommerce is a perfect way to implement a drop down cart in your Oxygen Website's header. Hover over the cart icon, and a fully featured WooCommerce mini-cart will drop down. Customers can even remove items from the cart via AJAX.
It'll inherit your global Oxygen Builder WooCommerce styles, and can be extended via Custom CSS. The dropdown feature is done via pure CSS, and everything is ready to go as soon as you install via the Hydrogen Copy/Paste method.
Don't need the cart, but still want the Ajax Cart Count element? Just delete the mini cart section!
