WooCommerce: Truncate Tag List @ Single Product Page

If you use WooCommerce product tags, it’s possible that a product may belong to 10 or more of them. When that happens, the single product page displays a long list of tag links, which may take too much space (see the below screenshot to visualize this).

Today’s snippet is indeed a way to truncate that list to – say – 3 tags only, and add a “+” to show the rest upon click. In this way if the customer is really interested in that they can expand the view, otherwise tags will take up a single line only. Enjoy!

PHP Snippet: Truncate Tag List & Show Read More @ Single Product Page

Note: the snippet truncates the tag list to 3 elements. Change slice(0, 3) and slice(3) accordingly if you need to use a different number of tags.

      var content = $(".tagged_as").html();
      var a = content.split(delimiter).slice(0, 3);
      var b = content.split(delimiter).slice(3);
      var html = a + "<span class=\'truncated\'>" + ellipses + "<a class=\'read-more\'>+</a></span><span class=\'truncated\' style=\'display:none\'>, " + b + "</span>";
      $(".tagged_as").html(html);
      $(".read-more").click(function(e) {
         e.preventDefault();
         $(".tagged_as .truncated").toggle();
      });
   ');
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
