Creating a metafield onto multiple products

You can create a metafield on a product - detailed steps in the article below - but it's also possible to create the same metafield on multiple products, without having to do the same steps on each product.

Before doing this action of creating the metafield, first select the products (onto which applying this metafield) in the central column of the App:

After hitting the add icon, enter the namespace and the key, as requested in the 2 popups.

You can now see the 3 lines of the new metafield in the grid - one by selected product (in this example).

You can now complete the information by choosing the type and entering the value on the first line, and then use the copy/paste options to complete the others.
