Returns
Type | Description |
|---|---|
| bool |
Remarks
If this method returns false the foldout arrow for an item will not be shown. Default behavior: if a search is active this method returns false (for search results, no foldout is required since the the results are shown as a flat list). If no search is active then by default it returns true if the item has any children, and false if it has no children.
