# Scrollbar and Scroll Behavior

The default `ScrollBehavior.dragDevices` of `PlutoGrid` is as follows.  
(dragDevices is a setting that allows scrolling by dragging to the set pointer type.)
```
// In case of Mobile
{
  PointerDeviceKind.touch,
  PointerDeviceKind.stylus,
  PointerDeviceKind.invertedStylus,
  PointerDeviceKind.unknown,
}

// In case of desktop
{
  PointerDeviceKind.mouse,
  PointerDeviceKind.trackpad,
  PointerDeviceKind.unknown,
}
```

Since `PointerDeviceKind.mouse` is set in Desktop, it is difficult to select the text of `PlutoCell` by dragging (because it is scrolled by dragging).  
In this case, you can customize `dragDevices` to remove `PointerDeviceKind.mouse`.
```dart
PlutoGrid(
  configuration: const PlutoGridConfiguration(
    scrollbar: PlutoGridScrollbarConfig(
      dragDevices: {
        // PointerDeviceKind.mouse,
        PointerDeviceKind.trackpad,
        PointerDeviceKind.unknown,
      },
    ),
  ),
),
```

If you remove `PointerDeviceKind.mouse` from Desktop to remove the drag-to-scroll action, horizontal or vertical scrolling can be done with the scroll bar.  
In the case of Desktop, the scroll bar appears when hovering the mouse over the scroll bar area.
