FilamentPHP v4.5 Guide: How to Use RichEditor @Mentions & New Features

Description :

The latest minor release of Filament v4 brings powerful enhancements to your TALL stack admin panels. While there are several quality‑of‑life updates, the RichEditor steals the show with built‑in support for dynamic mentions. Native @Mentions trigger dropdowns using @, #, or any custom character. Resizable images allow users to drag‑to‑resize images directly within the editor. Forced aspect ratios provide new validation and automatic cropping for file uploads. JS actions let you run client‑side scripts in your schemas without a network request. Implementing @Mentions in RichEditor is now incredibly straightforward using the new mentions() method and MentionProvider.
