| * Nested node is a child of `<cdk-tree>`. It works with nested tree. |
| * By using `cdk-nested-tree-node` component in tree node template, children of the parent node will |
| * be added in the `cdkTreeNodeOutlet` in tree node template. |
| * For example: |
| * ```html |
| * <cdk-nested-tree-node> |
| * {{node.name}} |
| * <ng-template cdkTreeNodeOutlet></ng-template> |
| * </cdk-nested-tree-node> |
| * ``` |
| * The children of node will be automatically added to `cdkTreeNodeOutlet`, the result dom will be |
| * like this: |
| * ```html |
| * <cdk-nested-tree-node> |
| * {{node.name}} |
| * <cdk-nested-tree-node>{{child1.name}}</cdk-nested-tree-node> |
| * <cdk-nested-tree-node>{{child2.name}}</cdk-nested-tree-node> |
| * </cdk-nested-tree-node> |
| * ``` |
