[mintlify]

Summary

• Documents the new mode property for navigation groups, which enables tree navigation on group root pages

Note

Low Risk
Low risk: documentation-only updates describing a new navigation.mode option; no runtime code or configuration defaults are changed.

Overview
Adds documentation for a new mode: "tree" navigation option that renders a tree listing on group root pages, including notes on recursive inheritance/overrides and JSON examples.

Updates the settings reference to include navigation.mode (defaulting to "auto") and applies the same documentation changes across the Spanish, French, and Chinese localized guides.

Closing: tree navigation mode (mode: "tree" property) has not shipped to production. This feature is currently in active development. If this feature ships in the future, a new docs PR can be opened at that time.
