Please tell me how to add specific menus to specific categories (sidebar-widget). I know how to add a menu, but this menu will show up in all catalog menus, and I need it only in one.
Or maybe there are other ways to implement switching between categories. I added photos as examples (it should not be possible to select two categories at the same time).
Then, try to use the Theme’s Layout Builder. You can create Custom Layouts for WooCommerce pages like Shop, Category. So, you can use that to create your own custom layouts for specific categories and choose the sidebar.
