Superstore comes with an optional left-hand sidebar on its collection pages. When enabled, this feature displays product filters, which can set up using tags in the Products admin. You can even set up filter groups, which make it easier for your customers to sort your products using subgroups.
Activate the sidebar
To show a sidebar on your collection pages, start by checking Show sidebar.
Select a filter option
Select how your Filters display with the corresponding dropdown. You can display them using By tag or By group.
If you display them By tag, all of the tags you have used will be displayed as checkable boxes in the sidebar. You can add and edit tags for each of your products in the Shopify admin.
You can find the tags section under Products > [Product name] > Organization > Tags
If you have a lot of products, you may want to enable subgroups. You can do this in the same Tags field of your product admin, but prepend existing tags with the name of the group then an underscore, like so:
It's important that you use this format—where the left side of the underscore is the group name and the right is the tag for the product. Spaces can be included on either side of the underscore, but no special characters.
Include navigation menus in the sidebar
Superstore comes with the option to add additional menus in the sidebar. They will not display unless you have checked Show sidebar in the Sidebar settings above.
To add a menu, click [+] Add menu or one of the existing menu blocks, then click Select menu to display options drawn from the Navigation settings.
Control how many navigation tiers appear
You can also customize the depth of your menus using the Menu depth visibility slider (maximum 3). This determines how many nested menu tiers are included in the sidebar menu.
