# hasVerticalScroller

A Boolean value that indicates if the combo box displays a vertical scroller.

```
var hasVerticalScroller: Bool { get set }
```

## Discussion

When the value of this property is <doc://com.apple.documentation/documentation/Swift/true>, the combo box displays a vertical scroller; when the value is <doc://com.apple.documentation/documentation/Swift/false>, it does not. The default value of this property is <doc://com.apple.documentation/documentation/Swift/true>. Note that the scroller is displayed even if the pop-up list contains fewer items than will fit in the area specified for display.

If you set this property to <doc://com.apple.documentation/documentation/Swift/false> and the combo box cell has more list items (either in its internal item list or from its data source) than are allowed by [`numberOfVisibleItems`](/documentation/AppKit/NSComboBoxCell/numberOfVisibleItems), only a subset are displayed. The [`NSComboBoxCell`](/documentation/AppKit/NSComboBoxCell) `scroll...` methods can be used to position this subset within the pop-up list.
