How to Create a Simple Currency Switcher Drop-Down
The quickest way to get a working currency switcher drop-down is the plain one: no skin, no JavaScript widget, just a native HTML select that the browser styles.

Placed in a page, a text widget or a template, that prints a simple drop-down listing every currency configured in the plugin settings. Choosing one reloads the catalogue in it.
A native select is worth choosing on purpose in two cases: on mobile, where the operating system draws its own picker and it always looks right, and inside themes whose JavaScript fights with the styled drop-downs.
For flags, colours and custom layouts use the [woocs] shortcode attributes or build the element in Smart Designer.
