Description

Group that contains children tree items.

The ngTreeItemGroup structural directive should be applied to an ng-template that wraps the child ngTreeItem elements. It is used to define a group of children for an expandable ngTreeItem. The ownedBy input links the group to its parent ngTreeItem.

<li ngTreeItem [value]="'parent-id'">  Parent Item  <ul role="group">    <ng-template ngTreeItemGroup [ownedBy]="parentTreeItemRef">      <li ngTreeItem [value]="'child-id'">Child Item</li>    </ng-template>  </ul></li>
