Using Avada Builder allows you to create any design you want for your WooCommerce Checkout page. Start with a Container / Column arrangement, and when you add your first Element, you will see the available Woo Design Elements at the bottom of the Elements dialog. There are five specific Woo Checkout Elements, as seen in the screenshot below – Woo Checkout Billing, Woo Checkout Order Review, Woo Checkout Payment, Woo Checkout Shipping, and Woo Checkout Tabs. The Woo Checkout Tabs Element contains the functionality of the other four Elements in one, and works in the same way as the default WooCommerce Checkout template. It’s also a good idea to use the Woo Notices Element at the top of your Checkout page to display any notices on the front end.
If however, you’d like to build a one page checkout, or just want a different design, using the four individual Checkout Elements will achieve the same functionality as the Woo Checkout Tabs Element. But the real magic of using the Avada WooCommerce Builder to build your Checkout page is that you can add the Elements in whatever structure and order you wish, and have complete control over the design and content of the page. You might want a Slider at the top, other Elements amongst the Woo ones, like the Title, Separator, or any other Elements that fit your circumstance and design ideas. It’s completely up to you.
