# Level 5

You are five levels deep: **Deep nesting → Level 2 → Level 3 → Level 4 →
Level 5**. This is the deepest page in the sample site.

Sitting on this page, every ancestor in the sidebar is expanded and marked as the
active trail, with this page highlighted as the current leaf — the same behavior
the unit tests in `tests/test_theme.py` pin for arbitrary depth.
