Flexible Content Extended for Advanced Custom Fields is a WordPress plugin designed to enhance the ACF Flexible Content Field. This plugin transforms the traditional layout list into a user-friendly modal interface featuring image previews, significantly improving the editing experience. Users can conveniently edit layout fields within the modal, making the process more intuitive and visually appealing.

The plugin accommodates image conventions, requiring images to be sized at 730 x 300 pixels and named according to the layout's designation with underscores replaced by dashes. By default, images are stored in a specific directory within the theme, though users have the option to filter this path as needed. Flexible Content Extended also allows for filtering of keys and images, providing flexibility for customization.
