How to sort a collection based on the availability of specific sizes

How It Works

1. Go to Variant-Level Inventory Settings

Navigate to your Kimonix Settings page and scroll down to the Variant-Level Inventory section.

2. Configure an Option Set

Create an option set to define which variant you want to prioritize:

• Click the + (plus) button to add a new option set
• Select the variants from the list that are most important to your collection
• Set a minimum quantity — products with stock above this threshold for the selected variants will be boosted

3. Apply to a Collection

Once your option set is configured, apply it to any collection:

• Go to the collection's sort settings
• Add the Variant-Level Inventory sorter
• Select the option set you created

Products with sufficient stock in the selected variants will be pushed higher in the collection, while out-of-stock variants will be deprioritized.

Example

If you sell clothing and want to prioritize products that have sizes M and L in stock, create an option set for those sizes with a minimum quantity of 1. Products with M and L available will appear higher in the collection.
