Angular 14 Tree

The Tree component is used to show hierarchical information which starts from the root item and proceed to its children and their respective children. Each item besides the root has a parent and can have children. The parent is the node which is higher in the hierarchy and the child the one that is lower. Siblings are items which have one and the same parent. Items can be expanded and collapsed.
