Tabs
Switches between views of the same thing on one page.
In Accessible first
See it live
npm run storybookWhen to use it
In Accessible first: Related views of one application, such as answers and documents. Not the steps of a form.
- Use it when: Related views of one object that people move between.
- Not when: Navigation to other pages (links), or steps of a task (progress).
Instead:
- Accordion: Stacked sections people can open together.
- Navigation menu: Other pages.
Words
- Use common words. Explain any term you must use.
- One idea per sentence. Put the action first.
- Never blame the person.
- Use: Continue, Change, Start, You. Avoid: Invalid, Utilise, Submit, Error code.
The labels components use, from the voice tokens:
content.action.commit: Continuecontent.action.cancel: Go backcontent.action.destroy: Deletecontent.action.retry: Try againcontent.action.empty-action: Start a new application
See Voice and tone for the whole voice.
Accessibility and keyboard
| Keyboard | What happens | Not |
|---|---|---|
| undefined | Arrow keys move between tabs; Tab moves into the panel. | undefined |
Test before you ship:
- It is a tablist; the selected tab owns its panel. undefined
Use it in code
npx open-ds add tabs
The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.
Tokens it reads
Tabs reads 14 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 Tabs's tokens to change Tabs alone.
Accessible 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.
