is it possible to add tags or custom fields (as a image) in product edit page?
That the Sellers can add existing products tags to their products.
for example. Seller is adding a new product Orange, and the tags would be fruit, bio.
Yes it it is possible. You can add tags in product edit page. Please navigate to product edit page. Then you will see the “Product Tags” field on the right of your page. I have added a screenshot to make it easy for you. Please check and let me know.
