You can easily add a product collection to any page using this element.
How to Use The Product Collection Element
In the right sidebar under "Elements" scroll down until you see the "Collection" element under "Shopify" heading.
Then simply drag the element where you would like to place it on your page.
In the right sidebar you can then change what collection is being displayed, the number of columns per row, and the number of products from the collection displayed.
💡 Note: the order of the products in your Collection Element may differ between the editor and the live page. This should be taken into account when creating content inside the product boxes of your Collection Element.
