# Sidebar Settings Menu

> The account and settings menu at the foot of an app sidebar. The signed-in person is the trigger; the menu opens upward with their profile and plan, settings links, an inline Light/System/Dark switch, a language submenu, help links with an unread count, an upgrade card with a usage meter, and log out. Collapsed sidebars get an avatar trigger and a menu that opens sideways.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/sidebar-settings-menu/sidebar-settings-menu.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/sidebar-settings-menu
```

Registry item JSON: https://www.assembli.design/r/sidebar-settings-menu.json (send `Authorization: Bearer <api key>`)
