Determines whether tree height is based on how many items are visible.
A Boolean value. The default is false, stating that vertical scroll bar will appear when there are more items to show.
When set to true, the height of the TreeView will change automatically so that all items are visible in current view. Expanding or collapsing items, will also change the TreeView height. Best usable when you want to use the browser or parent container scrollbar to scroll the content of the TreeView.
This property is accessed through 'auto-size' attribute of TreeView directive.
