Hello,
There is an option to show the categories in the shop page heading which is configured in the Theme Settings > Shop Page > Sidebars and Page Title Demo: https://woodmart.xtemos.com/shop/
Option “Categories in page title” will show the categories menu generated automatically based on all categories in the shop. It is not possible to manage this menu as other WordPress menus. By default sub-categories will be displayed as the drop-down list.
“Show current category ancestors” allows showing sub-categories and categories in the page.
Best Regards
