FA WP Admin Menu Icons allows you to use Font Awesome icons for WordPress custom post types and custom menu pages by passing the Font Awesome class string, just like using Font Awesome on the front end
Here’s an example:
register_post_type( 'custom_post_type', [
//...
'menu_icon' => 'fa-solid fa-thumbs-up',
//...
] );
Usage
`register_post_type()`
To use a Font Awesome icon for your custom post type with register_post_type(), use a Font Awesome class string for the $args['menu_icon] parameter:
register_post_type( 'custom_post_type', [
//...
'menu_icon' => 'fa-solid fa-thumbs-up',
//...
] );
`add_menu_page()`
To use a Font Awesome icon for your custom menu page with add_menu_page(), use a Font Awesome class string for the $icon_url parameter:
add_menu_page(
page_title: 'Custom Menu Page',
menu_title: 'Custom Menu Page',
capability: 'manage_options',
menu_slug: 'custom_menu_page',
icon_url: 'fa-solid fa-thumbs-up',
);
Custom Post Type UI plugin
To use a Font Awesome icon with the Custom Post Type UI plugin, use a Font Awesome class string for the Menu Icon field when adding or editing a Post Type
