Dropdown menu is not working

On the mobile menu, when the language switcher drop down icon is clicked, the flyout menu disappears . When the drop down icon is clicked it should show the English language sub menu . Can it be done with CSS ?. I don’t want to use any java script.

Hello discovernauts :slight_smile: ,
yes you could do it with bootstrap , it uses popper.js but you dont’have to write nothing in js.
Take a look at the documentation!

My site is built on wordpress. I just want to use css
