Collection index

Use a collection index when a reader needs to scan a bounded set of entries. Start from a section list such as layouts/links/list.html, then add filtering, sorting, tables, or pagination only when the content model makes those controls useful.

Includes#

• A clear section title and an ordinary linked result list
• The Filterable collection pattern for a data-driven collection with real filter values
• The Reference index pattern when readers compare structured records or need in-page section navigation

Empty and narrow states#

Give a filtered collection an explicit empty state. On narrow screens, preserve the result order and native list or table semantics instead of swapping the collection for unrelated cards.
