shadcn.io is an independent project built on shadcn/ui
Each trigger has an icon, a title, and a muted subtitle, with the chevron on the right. Documents starts open, and its subtitle names contracts, invoices, and briefs.
Use it when the title alone is not enough to pick a section. A single block of details can be a Collapsible. In React, Ark UI does not write the subtitles.

</Accordion>FAQ
Where do the category icons come from?
Each item stores FileTextIcon, FolderIcon, SettingsIcon or UsersIcon. The trigger renders it at size-4 with text-muted-foreground, shrink-0 and aria-hidden, in a gap-3 row before the text.
Where is the chevron?
AccordionTrigger draws its own chevron on the right. This trigger does not hide accordion-trigger-icon, and hover:no-underline is set on the trigger.
How is the subtitle marked up?
Title and subtitle stack in flex flex-col items-start text-start. The subtitle is text-sm text-muted-foreground.
Why is the answer indented?
ps-7 on AccordionContent matches the 16px icon plus the 12px gap-3, so the answer lines up under the title.
