onDragOver = (event) => {
        const {dataTransfer} = event;
        const {effectAllowed} = dataTransfer;
        
        if (/move|linkMove/.test(effectAllowed))
            dataTransfer.dropEffect = 'move';
        else
            dataTransfer.dropEffect = 'copy';
        
        event.preventDefault();
    }
