The page tree in the TYPO3 backend

The page tree is a hierarchical structure that represents pages and their subpages on a website, allowing editors and integrators to easily organize and manage content and navigation.

It is displayed on the left of backend modules with navigationComponent set to '@typo3/backend/tree/page-tree-element'.

Usage of the page tree is described in Getting Started Tutorial, Page tree.

The page tree can also be navigated via Keyboard commands (Tutorial for Editors).
