Demo: FontAwesome icons
The menu allows you to use FontAwesome icons in your menu. Just include the CSS for FontAwesome and you are ready to go.
With Font Awesome 5/6, always prefix the icon name with its style class (fas , far , fab , fad or fal ), e.g. icon: "fas fa-edit". Using just the icon name (e.g. icon: "fa-edit") is only kept for backwards compatibility with Font Awesome 4 and may not render correctly with newer Font Awesome versions/kits.
