Drag and drop in React File Manager component

20 Jan 20256 minutes to read

The File Manager allows files or folders to be moved from one folder to another by using the allowDragAndDrop property. It also supports uploading a file by dragging it from Windows Explorer to File Manager component. You can enable or disable this support by using the allowDragAndDrop property of File Manager.

The event triggered in drag and drop support are

• fileDragStart - Triggers when the file/folder dragging is started.
• fileDragging - Triggers while dragging the file/folder.
• fileDragStop - Triggers when the file/folder is about to be dropped at the target.
• fileDropped - Triggers when the file/folder is dropped.
