Add Font Awesome 4 icons to your WordPress menus and site without touching a single line of code! With this plugin, just add fa-(icon name) as a class/classes to your menu and the plugin will pull that out, put the icon before or after your link text, and wrap your link text in a span so you can show or hide it as you see fit.
In Font Awesome 4 Menus, we have added the ability to add multiple Font Awesome classes for multiple effects (eg, fa-home fa-fw fa-2x will add a fixed-width home icon at two times the normal size).
In addition, we have given you shortcodes to add icons to your posts and pages, as well as shortcodes to take advantage of the new stacked feature of Font Awesome 4.
