For Custom single product page, how to use the default currency switcher style?

Hi Support,

Can you advise me how to add the default currency switcher to the single product page?
(Screen Capture: https://jmp.sh/iSwuu8H, https://jmp.sh/bPvh9z5 )

As the Stamped.io review widget has broken the default currency widget into 2 part (Screen Capture: https://jmp.sh/KG0ozVp ), so instead of the default Single Product page style provided by my theme (Flatsome). I would like to create a custom single product page to overcome this problem.

However, when I try to use the shortcode as advised in https://villatheme.com/extensions/woo-multi-currency/ in adding the currency switcher, sounds none of them are the default style.

I’m thinking of either way to solve the problem
1) If the currency switcher (I mean the flag) can show below the review widget, plus show into single line (using the css you provided me yesterday), it’ll be perfect. (But I’m not sure whether it’s the problem on review widget and out of the scope of your support….)
2) Otherwise, if I can use the default currency switcher style in custom product page is good enough.

Thanks a lot for your guidance.

Cheers,
Joe
