Properties
hideSelectionElement
| Description | Defines whether the tree list item should display the selection element. |
| Type | boolean |
| Default | false |
icon
| Description | If set, an icon will be displayed before the text of the tree list item. |
| Type | string |
| Default | "" |
expanded
| Description | Defines whether the tree list item will show a collapse or expand icon inside its toggle button. |
| Type | boolean |
| Default | false |
indeterminate
| Description | Defines whether the selection of a tree node is displayed as partially selected.
Note: The indeterminate state can be set only programmatically and can’t be achieved by user interaction, meaning that the resulting visual state depends on the values of the indeterminate and selected properties:
- If a tree node has both selected and indeterminate set to true, it is displayed as partially selected.
- If a tree node has selected set to true and indeterminate set to false, it is displayed as selected.
- If a tree node has selected set to false, it is displayed as not selected regardless of the value of the indeterminate property.
Note: This property takes effect only when the ui5-tree is in MultiSelect mode. |
| Type | boolean |
| Default | false |
| Since | 1.1.0 |
hasChildren
| Description | Defines whether the tree node has children, even if currently no other tree nodes are slotted inside.
Note: This property is useful for showing big tree structures where not all nodes are initially loaded due to performance reasons. Set this to true for nodes you intend to load lazily, when the user clicks the expand button. It is not necessary to set this property otherwise. If a tree item has children, the expand button will be displayed anyway. |

- ariaPosinset: Defines an element's number or position in the current set of listitems or treeitems when not all items are present in the DOM. The value of each aria-posinset is an integer greater than or equal to 1, and less than or equal to the size of the set when that size is known. |
