I'm creating a store where each product has one or more "contributors" and each contributor has a contributor type (composer, arranger, artist, author, or editor). So, for instance, there may be an item with three contributors: John Doe, composer; Bob Smith, arranger; Jane Adams, arranger. I can't figure out a good way to store this information using the standard attribute types. Can anyone suggest a solution or, at least, point me in a potential right direction?
On magento 2 there is the manufacturer attribute which however is a single string. What you need should be a multiselect with attached source model so as to select one or more matches. Here the link https://devdocs.magento.com/guides/v2.4/ui_comp_guide/components/ui-multiselect.html
