Open in TWICE Admin

catalog/collections
Decide first how listings get into the collection, because everything else follows from it. A manual collection holds the listings you pick; a smart one holds every listing carrying the right tags. Use collections as merchandising rather than as a taxonomy. A listing sits in as many collections as you like, and joining one changes nothing about the listing itself.

Prerequisites

Required permissions: catalog:collection:create and catalog:collection:manage. All four system roles hold both.
Look at your tags before you build a smart collection. A smart collection is only as good as the tagging behind it, and inconsistent tags make it quietly wrong rather than visibly empty. Build it manually until tagging is a habit.

The walkthrough

1

Create the collection

Select Create Collection under Catalog → Collections. TWICE creates an empty manual collection and opens it, so give it a title and description on the General tab.
2

Set the type

Set Type on the General tab to Manual Collection or Smart Collection.Switch the type later whenever you change your mind. Your picked listings and your tag rules are stored separately, so each side survives a switch and comes back if you switch again.
3

For a manual collection, pick the listings

Open the Listings card on the General tab, select Select listings, and tick the listings that belong.Expect a manual collection to stay exactly as you left it. New listings never join on their own, so a campaign collection built in March is still March’s collection in September unless someone updates it.
4

For a smart collection, set the tag rules

Open the Smart Collection Rules card on the General tab and pick the tags that define membership. Then choose how they combine.Choose Any condition to admit a listing carrying at least one of the tags, which is the wider and more common setting. Choose All conditions to require every tag, which suits an intersection such as winter plus rental.Tag a listing and it appears; remove the tag and it leaves. Nobody maintains the collection after that, they maintain the tags.
Smart collections match on tags and nothing else. No rule reads price, attribute or availability, so build Under €50 manually or as a tag someone applies deliberately.
5

Publish the collection to its channels

Open the Publishing tab and turn on the channels the collection belongs on: Admin and Online store. Turning a channel off takes the collection off it and leaves its listings selling there on their own.
6

Fill in the Marketing tab

Set the page title, meta description and URL on the Marketing tab. Treat a collection as a landing page as well as a group: it is one of the few catalog pages a customer reaches from a search engine.Read more: Collection Marketing tab

Put it somewhere customers will see it

Feature the collection on the home page or add it to the storefront navigation. A collection nobody links to is a page nobody finds, and surfacing it is storefront work rather than something the collection does for itself.

How do I know it worked?

  • The collection lists the listings you expect. On a smart collection, read the membership rather than assuming the tags did what you meant.
  • The Publishing tab shows the channels you want, with Online store on for anything customers should browse.
  • The collection opens on the storefront and is reachable from somewhere a customer would look.
  • A newly tagged listing appears in a smart collection without anyone touching the collection.

Troubleshooting / common pitfalls

Cause: the tagging, almost always, rather than the rule. The listing carries no tag, carries a near-miss variant of one, or the rule sits on All conditions where you meant Any condition, and one missing tag then excludes the listing silently.What to do: check the match setting first, then the tags on a listing that should be in and is not. Fix tag drift at the tag level (winter, Winter, winter-2026) rather than adding more tags to the rule.
Cause: the tag is broader than the collection. A tag applied for one purpose pulls listings into every collection built on it.What to do: narrow the rule with a second tag on All conditions, or move to a more specific tag. Build it manually instead when you want to exclude one listing, because smart collections have no exceptions list.
Cause: a collection stores no order of its own, in either type.What to do: treat the storefront as the place sequence is decided, and read Design the storefront for what a collection block offers. Split a set into two collections when the distinction matters enough to control.
Yes, and it usually should be. Put the same listing in Skis, Under €50 and New this season at once, because collections do not compete with each other.Say it plainly to anyone arriving from a one-listing-one-category system, who otherwise builds far fewer collections than they should.
Cause: membership is not visibility. Check two things: whether the collection itself is on the Online store channel, and whether its listings are Public, on that channel, and available at the location the customer is browsing.What to do: open the Publishing tab first, then open one of the missing listings and check its publishing. A collection cannot make an unpublished listing visible.
