Hello,
Thank you very much for choosing our theme and for contacting us.
1. 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 subcategories and category in the page title in the way you want.
2. Navigate to Appearance > Widgets > Shop page widget area remove the filter you do not want and add one you need.
Best Regards
