During December 2025, Carretta focused on enhancing the Filament repository by developing a modal-based multi-record attach flow within the Attach action. This feature allowed users to select and attach multiple records at once, automatically deduplicating already-selected items to streamline bulk operations. Carretta implemented the solution using Laravel, Livewire, and PHP, ensuring robust functionality through comprehensive automated tests and updated documentation. The work addressed edge cases in multi-attach scenarios, refined related database queries for reliability, and maintained code quality with consistent testing practices. This contribution improved the efficiency and accuracy of user workflows for bulk attachments in Filament.
