File Uploader Widget Overview
The File Uploader Widget provides a drag-and-drop file attachment area in Buildocs UI Engine. Uploaded files are linked to the current form record and can be downloaded, previewed, or deleted directly from the widget. When files are uploaded, an event is sent to the backend.
Properties
The File Uploader Widget properties panel contains settings that control the field name, access permissions, and layout.
File Events
The File Uploader Widget fires an event to the backend when files are successfully uploaded. The backend can use this event to process the uploaded files, run validation, update related records, or return an error response.
