Add a <a href="http://fontawesome.com/" rel="nofollow ugc">Font Awesome</a> icon field type to Advanced Custom Fields.
<ul>
<li>Specify which FontAwesome icon sets to use (Solid, Regular, Light, Thin, Duotone, Duotone Sharp, Brands, and Custom Upload Icons) (Some features only available with FontAwesome 5.x or 6.x icons)</li>
<li>Create your own custom filtered list of FontAwesome icons to use with your fields. Use different custom icon sets with different fields</li>
<li>Returns Icon Element, Icon Class, Icon Unicode, or an Object including the element, class, unicode value, and SVG data (if applicable)</li>
<li>Optionally enqueues Font Awesome in footer where needed (when a FontAwesome field is being used on the page))</li>
<li>Integrates with the <a href="https://docs.fontawesome.com/apis/graphql" rel="nofollow ugc">FontAwesome GraphQL</a> for loading your <a href="https://docs.fontawesome.com/web/setup/use-kit" rel="nofollow ugc">FontAwesome Kits</a>, searching for icons, and loading the latest version of FontAwesome</li>
</ul>
Note: It is recommended to let this plugin enqueue the latest version of Font Awesome on your front-end; or include the latest version yourself using your <a href="https://docs.fontawesome.com/web/setup/use-kit" rel="nofollow ugc">FontAwesome Kit</a>; so that available icons in the admin area will be displayed properly on your sites front-end.
<h4>Compatibility</h4>
This ACF field type is compatible with: 
* ACF 5.7+ 
* FontAwesome 4.x, 5.x, 6.x and 7.x fonts
<h3>Optional Configuration</h3>
<h3>Filters</h3>
<ul>
<li>ACFFA_always_enqueue_fa: Return true to always enqueue FontAwesome on the frontend, even if no ACF FontAwesome fields are in use on the page. This will enqueue FontAwesome in the header instead of the footer.</li>
<li>ACFFA_admin_enqueue_fa: Return false to stop enqueueing FontAwesome in the admin area. Useful if you already have FontAwesome enqueued by some other means.</li>
<li>ACFFA_get_icons: (Applies to FontAwesome 4.x and 5.x icons only) Filter the array of icons and icon details loaded from the database</li>
<li>ACFFA_get_fa_url: Filter the URL used for enqueuing FontAwesome in the frontend and admin areas of the site.</li>
<li>ACFFA_override_major_version: Filter to manually set the ‘major’ version of FontAwesome to load (accepts either 4, 5, or 6). NOTE: This filter must be registered before any calls to ACF get_field() function are made.</li>
<li>ACFFA_fa_api_key: Filter to programmatically set the FontAwesome API key.</li>
<li>ACFFA_fa_kit_token: Filter to programmatically set the FontAwesome kit token.</li>
</ul>
