Superstore comes with a Collection toolbar, which allows customers to sort products and select how many products to show per page. When enabled, this will use the number you've selected under Products per page as the default, but allow them to view other numbers as well (24, 36, and 48).
Select the features through the theme editor
The Collection toolbar will include all available features by default. To locate these settings, navigate to any collection page in the theme editor, open Collection page in the left-side settings, and scroll down to Collection toolbar.
Allow customers to sort products
Enabling Show "Sort by" dropdown will show an option like this embedded in a contrasting bar between the collection image and your product tiles.
When clicked, users will be able to sort products by Featured, Price: Low to High, Price: High to Low, A-Z, Z-A, Oldest to Newest, Newest to Oldest, and Best Selling.
Allow customers to control the number of products presented
You can also Show products per page links in the same bar. This means that users will be able to select how many products they want to view, per page, at a time.
Allow customers to change the view
Another option to enable is Show grid/list view toggle. This lets your customers switch between a grid layout of products and a list view in a column. The list view provides a description of the product on desktop for customers that want to know more about each product at a glance. On mobile, both the list and grid view contain the same information.
Collection page templates
When setting up collections in the Collections admin, you may notice that there are selectable templates in the Theme templates section. These serve the Collection toolbar features and should not be assigned to any collection.
The exception to this is the Minimal collection template, which is an alternative option to consider.
