I think I actually just figured it out! I did it this way because I didn't want to affect the mobile menu when I clicked on the folder, so this was a way around that. I did this for the 'work' tab/folder/dropdown option in the navigation of my portfolio/design site because I didn't want the folder to link to anything at all. Let me know if you have questions!
@media screen and (min-width: 640px){
a.Header-nav-folder-title.Header-nav-folder-title--active {
pointer-events: none;
cursor: default; }
}
Note: I also used this site for reference/help.
