LangShop allows Shopify merchants to add a currency button at the storefront.
From your LangShop Admin, open Settings -> Currencies.
Under the Currencies title, open the Switchers section.
Here, you can manage recommendations banners, language & currency selectors. On the left sidebar menu, find the Currencies Selectors box -> click Add.
By default, the currency selector will appear at the bottom right. Make sure to save changes.
If you want to change the position of the switcher, find the Advanced tab -> Selector position. There are four standard variants you can place your button to, which are: bottom-right, bottom-left, top-right, top-left.
To add a currency button to a custom position, for example, header or footer, select Relative position, copy the selector snippet (find the snippet code at the bottom of currencies settings), and place it to the right template in the theme code.
There are three tabs you can customize too. The Content tab gives you access to name the switcher, display icons or titles, change the flag icon type, use currencies flags or symbols, display currency's full name or currency shortcode. The Style tab offers colors, fonts, and sizes for your currency button. The Advanced tab allows to change the position of the switcher, define the offset position, manage the visibility of switchers on different devices, like mobile, tablet, and desktop. If you create separate currency buttons for desktop, for example, make sure to hide buttons on mobile and tablet by unchecking the visibility box.
