 Use the `expanded` property to control the default state of a nested group in the navigation sidebar.
 
 - `expanded: true`: Group is expanded by default.
 - `expanded: false` or omitted: Group is collapsed by default.

   The `expanded` property only affects nested groups--groups within groups. Top-level groups are always expanded and cannot be collapsed.

+### Tags and labels
+
+Use tags to highlight important navigation items and draw attention to new, updated, or deprecated content. Tags appear as small labels next to navigation group names in the sidebar.

+
+#### Adding tags to navigation groups
+
+Add the `tag` field to any navigation group to display a label. Tags work with all navigation elements that support groups, including tabs, anchors, dropdowns, and products.
+
+```json
+{
+  "navigation": {
+    "groups": [
+      {
+        "group": "Getting started",
+        "icon": "play",
+        "tag": "NEW",
+        "pages": ["quickstart", "installation"]
+      },
+      {
+        "group": "API v2",
+        "icon": "code",
+        "tag": "BETA",
+        "pages": ["api/v2/overview", "api/v2/endpoints"]
+      },
+      {
+        "group": "Legacy API",
+        "icon": "archive",
+        "tag": "DEPRECATED",
+        "pages": ["api/v1/overview"]
+      }
+    ]
+  }
+}
+```
+
+#### Tag best practices
+
+Use tags strategically to guide users to the most relevant content:
+
+- **NEW**: Highlight recently added features or documentation sections
+- **BETA**: Indicate features in testing or early access
+- **UPDATED**: Draw attention to recently revised content
+- **DEPRECATED**: Mark outdated features that will be removed
+- **PREVIEW**: Show experimental features available for early feedback
+- **PRO** or **ENTERPRISE**: Denote premium or tier-specific features
+
+Keep tag text short and descriptive. Tags longer than 12 characters may be truncated on smaller screens.
+
+#### Tags in different navigation contexts
+
+Tags work consistently across all navigation elements:

+#### Styling considerations
+
+Tags inherit your documentation's primary color scheme by default. The appearance adapts automatically to light and dark modes based on your theme configuration.
+
+<Note>
+  Tags are purely visual indicators and do not affect navigation functionality or page accessibility. Users can still access all pages within tagged groups normally.

 Tabs create distinct sections of your documentation with separate URL paths. Tabs create a horizontal navigation bar at the top of your documentation that lets users switch between sections.

 ## Nesting
 
 Navigation elements can be nested within each other to create complex hierarchies. You must have one root-level parent navigation element such as tabs, groups, or a dropdown. You can nest other types of navigation elements within your primary navigation pattern.
 
 Each navigation element can contain one type of child element at each level of your navigation hierarchy. For example, a tab can contain anchors that contain groups, but a tab cannot contain both anchors and groups at the same level.

 ### Enable auto-navigation for groups
 
 When a user expands a navigation group, some themes will automatically navigate to the first page in the group. You can override a theme's default behavior using the `drilldown` option.
 
 - Set to `true` to force automatic navigation to the first page when a navigation group is selected.
 - Set to `false` to prevent navigation and only expand or collapse the group when it is selected.
 - Leave unset to use the theme's default behavior.
