+Jinja templates are rendered in Markdown and page titles with project settings and `extra` variables.
+
+<div class="mdx-plugin-settings" markdown>
+
+| Setting | Default | Description |
+| ------- | ------- | ----------- |
+| `enabled` | `true` | Jinja rendering and data loading are enabled. |
+| `data` | `null` | Comma-separated data directories, relative to the project root. When unset or empty, `_data` and `<docs_dir>/_data` are searched. |
+| `jinja_options` | `{}` | Options passed to the Jinja environment, including template delimiters. |
+
+</div>
+
+**Differences**:
+
+- Data directories and files that resolve outside the project root are silently skipped, including symlink targets.
+- YAML data is loaded with `SafeLoader`. Python-specific tags such as `!!python/name` and `!!python/tuple` are rejected.
+- YAML dates are converted to strings for theme templates. Their original Python types are retained during Markdown rendering.

+Navigation order, section titles, and visibility are controlled through page metadata.
+
+<div class="mdx-plugin-settings" markdown>
+
+| Setting | Default | Description |
+| ------- | ------- | ----------- |
+| `enabled` | `true` | Weighted navigation is enabled. |
+| `section_renamed` | `false` | Section names are replaced with their index page titles. |
+| `index_weight` | `-10` | Weight assigned to index pages within their section. |
+| `default_page_weight` | `0` | Weight assigned to pages with missing or invalid `weight` metadata. |
+| `reverse` | `false` | Items are sorted from highest to lowest weight. |
+| `headless_included` | `false` | Hidden pages are included in `nav.pages`. Empty index pages remain excluded. |
+| `warning` | `true` | Warnings are emitted for invalid metadata values. |
+
+</div>
+
+**Differences**:
+
+- Weights are applied after other navigation plugins, regardless of their order in `plugins`.
+- Resolved page metadata is used, including values inherited through [`meta`](#meta) and changes made during Markdown rendering.
+- Previous and next page links within hidden sections are rebuilt after hidden children are removed.
