Some theme settings won't show until you're viewing the page in the theme editor preview window to which they relate - product, collection, article and blog settings all fall into this category. Be sure to navigate to the page you want to edit, to see the options available in the left sidebar of the theme customizer!
Choose from grid or collage for your collection listing pages. It's also possible to create additional collection listing pages with your choice of collections. To create multiple collection listing pages, follow these steps. Just skip the "Create your new page template" section, as the theme already includes a "page.list-collections" template.
Enable infinite scroll to load in new products as the user reaches the end of a page and as with the collections list choose from a grid or collage layout.
Depending on your product image sizes, you might prefer to keep your header and logo bar above the product images. This is possible using the header overlay style settings - choose to push the content down, or have a tinted overlay or show your alternative logo.
Use the overriding description alignment setting to change the arrangement of your product description within the restricted reading width column on your product pages.
Choose traditional drop downs or list out your variant options. When using the listed layout, sold out single-variant products or variants which are unavailable will be shown as crossed through.
Change the cart type here to toggle whether the user is taken to the Cart page immediately after clicking the buy button on if they remain on the current page (this option is sometimes known as AJAX add to cart)
