Hello liughost,
The documentation exposes events for explicit user actions like moving, downloading, deleting etc., but there is no separate configuration prop for drag‑and‑drop or upload functionality. The reason is that drag‑and‑drop and upload is a built‑in, permanently enabled behavior of the filemanager.
While there's no specific configuration for dragging and uploading files, the upload and drag process itself is still customizable through general upload events. The events, like move-files and download-file, represent operations you might need to intercept or block.
