Hi there,
Thanks for writing in!
Regretfully, this particular customization request would fall outside of the support we offer. It requires the custom development. You may wish to consult a developer to assist you with this.
Thanks for understanding.
So, although the evolve theme includes Font Awesome icons, can I conclude that the way the evolve theme menus works, it would require custom coding to show Font Awesome icons correctly in the menus.
