[Dawn] How to create a section to display products, collections, and blog posts together in the Shopify theme "Dawn"

Shopify allows you to add your own sections. For example, here is a section example that allows you to display a mixture of articles, products, and collections, like a media site, instead of a list of products or blog posts. You can also change the number of columns displayed and combine them to suit your theme.
