While the Debut theme on the Shopify theme store is excellent for starter entrepreneurs who want to get into the Shopify game. There are limitations of functionality within the theme which can cause UX issues to your customers.

Having a currency converter within the header will allow your customers to easily change the currency of the store without having to use any apps that may slow down your store. The currency converter will link to the available currencies you accept on your Shopify store.

Lets get down to business, the guide will go through both the desktop header and the mobile drop down navigation, this will ensure the currency converter will show for both types of customers, whether on their mobile or their desktop.

Go to the Shopify theme edit code. Head over to the Section folder and click Header.liquid.

Scroll down to line 114. Right before the button, add the below code

<span class="desktop-currency">
    {% form 'currency' %}
    {{ form | currency_selector }}
    {% endform %}
<!---Coded by bluish.io --->

Scroll down to line 222, 233, and 244. Right after {% endfor %}, add the below code.

<li class="mobile-nav__item mobile-currency">
    {% form 'currency' %}
    {{ form | currency_selector }}
    {% endform %}
<!---Coded by bluish.io --->
