# NSSplitViewItem.CollapseBehavior.preferResizingSplitViewWithFixedSiblings

The item’s preference is to keep the other panes at their current size and position onscreen, potentially growing or shrinking the window in the direction to best preserve that.

```
case preferResizingSplitViewWithFixedSiblings
```

## Discussion

The split view item breaks this preference in full-screen mode, and to keep the window fully onscreen during resizing.
