 | `collapse-level` | Whether to show sidebar navigation collapsed by default. The default is 2, which shows the top and next level fully expanded (but leaves the 3rd and subsequent levels collapsed).                                                                                 |
 | `pinned`         | Always show a title bar that expands to show the sidebar at narrower screen widths (true or false). Defaults to false, and uses [headroom.js](https://wicky.nillia.ms/headroom.js/) to automatically show the navigation bar when the user scrolls up on the page. |

+
+To use a specific sidebar on a page or a group of pages, specify the `sidebar` ID in the front matter of the page or in the `_metadata.yml` file.
+For example, to include the tutorials sidebar on a page, add the following to the page's front matter:
+
+```yaml
+sidebar: <id>
+```
