When to use it

In Multi-brand: One block of extra detail on a form, such as more options. Not for frequent questions; accordion holds those.

• Use it when: A single block of extra detail people may want: more filters, advanced options.
• Not when: Several stacked sections (accordion), or content everyone needs.

Instead:

• Accordion: A stack of sections.

Words

• Shared structure: object, state, next step.
• Brand tone lives in headlines and marketing copy, not in errors.
• Errors and confirmations read the same in every brand.
• Use: Get started, Plan, Order. Avoid: Brand-specific words in errors, Jargon.

The labels components use, from the voice tokens:

• content.action.commit: Save
• content.action.cancel: Cancel
• content.action.destroy: Remove
• content.action.retry: Try again
• content.action.empty-action: Get started

See Voice and tone for the whole voice.

The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.

Tokens it reads

Collapsible sets no colors, corners or shadows of its own; it takes them from the components inside it.
