Custom CSS: How to remove underline from nav "folder"

I added custom CSS code to create an underline while hovering on linked text, including navigation. What I would like to do is remove the underline while hovering on a "Folder" in Navigation as it doesn't actually link to anything. How would I do this? 

The example I'm referring to in the image is "Visit Us" should not be underlined while hovering, but Denali Brewpub and Tasting Room should be. 

Here is the CSS code I have:

h1 a:hover, h2 a:hover, h3 a:hover, p a:hover,.header-nav-item a:hover, {
  text-decoration:underline;
}

@HaileyDeReamer You'll need to get more specific with your hover selectors, can you share a link to the page you need help with? If it's still in development, you can add a password and share it here.

@HaileyDeReamer ok try adding this to custom CSS:

a.header-nav-folder-title:hover {
	text-decoration: none;
}

If that doesn't work, try adding !important...

That worked! Thank you!
