Reply To: How to display subcategories in the page header.

Hi jay-9133,

According to the screenshot, it seems you are using Custom Product layouts. If so, please go to Layouts > Layouts then edit product layouts and you can use Archive description to display categories’s descriptions https://ibb.co/16BTp4Y

And please note that you can put descriptions inside Page Title area because these are 2 separate sections.

Regards,
