Navigation Folder Spacing

Is there a way to add spacing between navigation links in the drop down menu? cc: @tuanphan
In addition to adding spacing between the folder links, I'd like to add additional padding to the folder itself so it's a little larger in size. You can see current site & mock in this post.

Thanks @tuanphan that helped. There's some awkwardness with alignment and I had to make some adjustments.

You can see the code adjustment I made and also the image of how it displays.
 

span.header-nav-folder-item-content {
    font-size: 16px;
    margin-bottom: 10px;
  	margin-right: 20px;
  	margin-left: 20px;
    display: inline-block;
}

The code I tested on my site, so it can/can't work on your site. What is your site url? I can check easier

Align like this?

Don't remove any code in your current code.

Add this CSS code

.header-nav .header-nav-item--folder .header-nav-folder-content {
    left: calc(~"-20px - 1em") !important;
}

Yes, @tuanphan that worked! Thank you so much 😊
