How can I add a metafield on a product?

New metafields can be added onto your products via the dedicated panel in the Property column (right handside) called Metafields:

Once you've selected a product, existing metafields will be displayed in this grid.

To add a new metafield, click on the add icon on the toolbar:

Then enter the requested information: namespace > key

The corresponding line of the new metafield is now created, and you can complete it by selecting the type and entering the value in the corresponding fields - double click to edit the cells.

And this is it, your metafield is created on that product.

If you need to create the same metafield for multiple products, please refer to the article below.
