Sidebar
The side navigation of an app, open while people work.
Left out of Content first Sidebar is app navigation, not a website's main navigation. Content first is a public site; navigation menu carries the site sections and sheet the phone menu. Use instead: Navigation menu, Sheet
See it live
Start Storybook to see it live:
npm run storybookWhen to use it
- Use it when: Apps with several sections people move between all session.
- Not when: A website's main navigation (navigation menu), or a few sections that fit in tabs.
Instead:
- Navigation menu: Website navigation.
- Tabs: Views of one thing.
Variants
What each variant is for in any design system, then what Content first decided and why. Each sample is the live story with that variant set.

Words
- Write to one person: "you", not "users".
- Short sentences with room to breathe.
- Explain why before asking for anything.
- Use: Read, Save for later, You, Next issue. Avoid: Click here, Submit, Users, Content.
The labels components use, from the voice tokens:
content.action.commit: Savecontent.action.cancel: Not nowcontent.action.destroy: Removecontent.action.retry: Try againcontent.action.empty-action: Browse guides
See Voice and tone for the whole voice.
Accessibility and keyboard
Test before you ship:
- It is a navigation landmark; the current section is marked; collapsing keeps names for icons. undefined
Use it in code
npx open-ds add sidebar
The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.
Tokens it reads
Sidebar reads 113 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Sidebar's tokens to change Sidebar alone.
Changes with theme
Content first decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
