wordpress show category and subcategory in menu
If you are using a normal WordPress menu (wp-admin->Appearance->Menu) you can add categories to the menu.
If the categories aren’t shown on the left you need to enable them in the ‘screen options’ which is located at the right-top on the menu page.
Then you can just add categories as you want to the menu.
