Create a searchable / filterable product metafield

Thanks to the recent update in Shopify's API, merchants can create up to 50 indexable metafields that can be used to filter products.

To create one, go to Settings (1) -> Custom data (2) -> Products (3) -> Add definition (4):

Next, specify the namespace/key combination (5), select a supported metafield type (6), and enable the "Filtering for products" option (7):

Currently, the following metafield types are supported:

1. Single line text / Single line text (list)

2. Product reference / Product reference (list)

3. True or false (boolean)

4. Collection reference / Collection reference (list)

5. Page reference / Page reference (list)

6. Metaobject reference / Metaobject reference (list)

7. ID

Press the Save button (8):

Then, the Add filter button (2):

Next, select a previously created metafield (3):
