GitLab 18.9 introduces a collapsible, resizable file tree browser panel in the repository view, bringing an IDE-like navigation experience to the web interface. The panel stays visible alongside file and directory views, expands parent directories automatically when navigating to nested files, and syncs with the current location. Key features include keyboard-first navigation following the W3C ARIA treeview pattern, filename filtering via a global search dialog, responsive behavior across desktop and mobile viewports, and pagination support for large repositories. Available now on GitLab.com, Self-Managed, and Dedicated.
