To display the currency switcher in WordPress menus such as header and top menu, please go to Appearance > Menus.
There you can find a menu item called YayCurrency. Just add it to the position that you see fit.
Then, give the menu title a custom text and click Save Menu.
On the front page, the currency switcher automatically shows in the order and design that you have set up in the currency manager tab.
It’s a currency dropdown that can be displayed on the Header, or Footer, in addition to WooCommerce product page and sidebar. When the customers change the currency in one of those spots, the new currency applies site-wide.
