You can highlight one of the reviews shown in the product by going to “Reviews” and clicking the “Featured” button of the review you chose to highlight.
To highlight the review, make sure the value isn’t set to zero in the “Featured reviews” field. Through this option, you can set up the maximum number of reviews to highlight.
Highlighted reviews have a different style and come before the others.
If the number is higher than the quantity of provided reviews to display, the ones to highlight will be taken randomly among the”featured” reviews.
