I’m sorry… I can’t find this option anywhere. Can you guide me on the path please?
It’s when you create a new product.
Go to Catalog
Then Manage Products
On the top right, click to add new product
Once you’ve selected the attribute set and the product type, you’ll see the option labelled ‘Catalog Input Type for Store Owner’. Just select ‘multi-select’ from the dropdown.
