Here’s what we want, the ability to insert cute little icons into our menu. We’ve made this really easy.
First, go to Font Awesome’s site here.
Scroll down until you see the search box. Search for whatever icon your heart desires. I searched for a heart icon and got several results.
Then I clicked one heart icon.
Select the fa-heart text and copy it by hitting command c.
Go back to your WordPress dashboard under appearance / menus. Just paste the text for the heart icon into your menu title.
Your heart should appear in your menu. Viola!
