Cart

The cart every page has, with no attribute to put it there. Read it with data-next-query (cart.total), list its lines with data-next-each (cart.lines), and change it with actions. next.query('cart') and every cart.* event carry the same object.

CODE

<span data-next-query="cart.total"></span>

<div data-next-each="cart.lines">

</div>
