How to add animation to the currency selector

[CreatorTim]

Hey, does anyone know how I can add an animation to the currency selector on mobile?

I’d like a smooth slide-down & up animation when I click on it. Right now, it just pops open, and it looks awful.

I’d like this for both the header and footer.

Here’s my store: https://1049xn-ya.myshopify.com/

I only need this for mobile

Thanks a lot, I’d really appreciate the help.
