# verticalMotionCanBeginDrag

A Boolean value indicating whether vertical motion is treated as a drag or selection change.

## Declaration

```swift
var verticalMotionCanBeginDrag: Bool { get set }
```

## Discussion

Discussion The default value of this property is true, which indicates that a vertical drag motion begins a drag. In this case a vertical drag will drag-select rows. Most often, you would want to disable vertical dragging when it’s expected that horizontal dragging is the natural motion. note: Horizontal motion is always a valid motion to begin a drag.
