Similar to how you can add class names to submission and evaluation form fields to style them, it would be nice if you could do the same for navigation menu items in Public Settings > Websites > Menu and Pages.
Common use case is wanting to draw attention to a "Enter Now" link. Currently those are implemented based on the order of the items in the menu which isn't great.
Quick mockup:
I like the theory, I'm wondering if some admins might be confused or concerned if they see "CSS Class", since as far as I know we don't have a publicly available list of style snippets.
Another option would be to include an "Advanced" section under the Type dropdown, where more advanced users could enter the CSS class. This would also future proof things a bit if additional advanced features were added later.
