Country and language selector UX guidelines
There are three main locations to place country and language selectors:
Near the customer account links
If the customer account links are placed near the cart, then the currency selector should be placed, and styled, in the same fashion. The following shows examples with customer accounts enabled, and disabled:
Customer accounts enabled
Customer accounts disabled
Near the cart
If the customer account links are widely separate from the cart, then the country selector should be placed near the cart for better visbility:
Aside from the navigation links, the cart is the most important element, so the country selector should not compete with it. Given that, if the cart is on the right-hand side of the page, then the country selector should be placed to the left of the cart to maintain ease of access for customers.
Don't do this
Inside a navigation drawer
If the country selector is inside a navigation drawer, then it should be treated as a utility or footer link, as opposed to a navigation link.
