Collections and looks

Datum treats collections in three ways: ordinary collections, categories for large ranges, and looks for small styled sets. Each comes from the template you assign to the collection.

Collection templates

Open a collection in Products › Collections and choose its theme template in the Theme template box.

TemplateUse it for
Default collectionMost collections.
categoryLarge ranges, typically 50 products or more. A category page's breadcrumb reads Home / All products / the category.
lookSmall curated sets of about 2 to 8 products, styled together. Looks show on the product page, in the Lookbook section and on their own Look page, and never in collection lists.

Any template whose name starts with category or look counts, so you can make variations of either.

Looks

  1. Create a collection with the products of the look and assign it the look template.
  2. Give it an image. For control over how the picture is cropped, create a collection metafield in Settings › Custom data › Collections: name it Look picture, with namespace and key custom.look_picture and type File (images). Pick the picture there for each look, and set its focal point in Content › Files › the image › Edit › Focal point.
  3. The product page's Looks section shows the looks a product belongs to. The Lookbook section shows the newest looks, or the ones you choose with Look blocks.

Theme settings › Looks sets how many looks show, how many of their products are listed, and how the picture is laid out. A look shows its picture in this order of preference: a Look block's image, the Look picture metafield, the collection's own image.

Shopify keeps no focal point for a collection's own image, so a look that uses it shows the whole picture instead of cropping it.

A line of links above the product grid lets shoppers move between related collections. It comes from a menu:

  1. In Online Store › Navigation, create a menu whose items are collections, nested up to three levels (for example Women › Clothing › Dresses).
  2. Pick it in Theme settings › Collections and filters › Collection navigation, or name the menu so its handle is collection-navigation.

On All products the top level shows. A collection with children shows "All" and its children; one without children shows its siblings. Only links to collections count; collections with no products are left out. Without a menu, All products lists your categories automatically.

Editorial images

Large pictures can sit among the products of a collection, every so many products, to break up long grids.

  1. Create a menu whose items are collections or products, in the order they should appear.
  2. Pick it in the collection section's Editorial images menu. To give one collection its own, name a menu editorial- followed by the collection's handle (for example editorial-summer); All products uses editorial-all.

A collection item shows the collection's image and title. A product item shows the product's second picture; add the tag grid-image:3 to show its third picture instead (any number works). A picture 3:2 or wider spans the whole row with its words on it; other pictures take two cards' space. Editorial images hide while filters are in use.

Theme settings › Collections and filters sets where they appear (First image after this many products, Then one every, Images per page at most) and what shows without a menu.

Filters

Filters are set up in Shopify's free Search & Discovery app (Apps › Search & Discovery › Filters): add, name and order them there. Datum shows each filter as a row that opens its values:

Turn filtering and sorting on or off in Theme settings › Collections and filters › Collection and search pages.
