Collections are groups of products that share a theme: summer, women's, under $20, new arrivals, gifts for him, whatever makes sense for your store.
Ask Sloane
"Sloane, create a collection called New Arrivals and add everything I've added in the last month" works. You can also ask Sloane to suggest collections if you have a big catalog and do not know where to start.
What a collection needs
A name and optionally a cover image.
Products and nested collections
A collection can contain products, other collections or a mix of both. This is useful when you want a broad grouping like "Gifts" that then breaks down into "Gifts for him" and "Gifts for her". A product can also belong to more than one collection.
Drag and drop to reorder. Put your strongest items first.
Public or hidden
Each collection has a Public toggle, the same as products. Public collections appear on your storefront. Hidden collections are useful for seasonal groupings or behind-the-scenes organization. Empty collections do not appear to customers.
