Want to make dropdown menu always visible

Hi there, 

I'd like to make this website show one of the two drop down menus at all time (not just on hover) - so if a page on the Svenska side is active, the Svenska menu remains visible, and if a page on the English side is selected the English menu is showing. Is this possible?

Thanks for your help! 

@feedbacksolo Try adding this to your custom CSS:

.header-nav-list .header-nav-item:first-of-type .header-nav-folder-content {
	opacity: 1;
}

Thanks so much, I really appreciate the help! 

The code you shared made it so the Swedish side was always visible even if you were on an English page, so I modified it so they were both visible (by taking out "first-of-type"). But with both the original code and the change, the links in the menu that it shows aren't clickable unless you move the cursor over them from above (through the word Svenska or English) - if you just hover over the links, they aren't active. Do you know if there is a way around that?

Fantastic, thanks very much!
