Cluster Definitions
A cluster definition decides which product attributes become the variant selectors of a cluster, for example Color and Size, and how each one is shown in the storefront. You create the definition first and pick it when you create a cluster.
Before you begin
- You need the Product role to view cluster definitions.
- Creating or deleting cluster definitions requires Owner access on the Product role.
- Editing cluster definitions requires non-viewer access.
Cluster definitions control which product attributes form the variant selectors for a cluster. Navigate to PIM > Cluster Definitions to view all definitions.

Create a cluster definition
- Click New Cluster Definition.
- Enter a Name in UPPERCASE_WITH_UNDERSCORES format (for example, PRODUCT_MODEL_SHIRT). This name cannot be changed after creation.
- Click Add product filters to open the attribute picker.
- Select the product attributes that form the variant selectors (for example, Color and Size).
- For each attribute, choose a Display Type:
| Display type | Description |
|---|---|
| Color | Color swatches |
| Dropdown | Standard dropdown menu |
| Image | Clickable image tiles |
| Radio | Horizontal option tiles |
- Drag and drop to set the priority order. This determines the attribute selection sequence in the storefront.
- Click Save.
Edit a cluster definition
Click any row in the cluster definitions list to open the edit dialog. You can add or remove product filter attributes, change display types and reorder attributes by dragging. The definition name cannot be changed.

Delete cluster definitions
- Select one or more definitions using the checkboxes.
- Click Delete and confirm.
