ACF Simple Tooltip is a lightweight WordPress plugin designed to enhance the user experience when working with Advanced Custom Fields (ACF). It effectively displays field instructions as tooltips, minimizing visual clutter in the WordPress dashboard. The plugin utilizes only two lines of JavaScript to add necessary classes to ACF field labels, ensuring that the tooltip functionality is both efficient and unobtrusive. The styling and hover effects for the tooltips are managed entirely through CSS, making it a straightforward addition to any WordPress setup.

The plugin is particularly beneficial for developers managing a large number of ACF fields, as it maintains optimal performance without the load-time issues that can arise with more complex tooltip solutions. Installation is simple, with the JavaScript and CSS automatically enqueued on any post.php page within the WordPress dashboard. This solution enables a cleaner interface while providing essential guidance for data entry personnel.
