Sources element: hideTrigger for callers with their own trigger (blocked on #7962) - #8001
JesseWebDotCom wants to merge 5 commits into
Conversation
Sources gains an optional layout?: "grid" | "list" prop (default "grid", every existing usage unchanged). "list" renders one compact line per source instead of the two-column card grid, for a reply with more sources than the grid comfortably fits, or a caller that wants the list itself denser. Also fixes a real bug found adding the list layout: both layouts keyed each row by source.domain, so two different pages on the same site in one sources array produced two rows with the identical React key. Both layouts now key by array index instead. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Two screenshots (grid, list) rendered from a standalone demo using the same generic sample data as apps/docs/components/demo/elements/sources.tsx, for the pull request description only. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…ings - Both text spans in the list row now shrink (min-w-0 + truncate), the domain also capped at max-w-[40%], so a long title or domain can't widen the row past its container. - Added a colocated test file covering the default grid, the list layout, duplicate domains, and a long title/domain pair. - Documented `layout` in apps/docs/content/elements/sources.mdx and updated its stale "grid only" / "four props" language. - Added docstrings to Sources and SourceGlyph. - Dropped the changeset: @assistant-ui/ui is private, and the changeset config rejects a changeset naming it. Closes assistant-ui#7988 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
A caller with its own control over `open` (a tab, a sibling toggle) currently gets a second, redundant disclosure affordance stacked alongside Sources' own built-in trigger. `hideTrigger` (default false) omits it, rendering only the panel content. `SourceGlyph`, the shared domain-initial glyph, is exported for a caller building that custom trigger to reuse it.

With hideTrigger, onOpenChange becomes unreachable — nothing in the element can call it — yet the type still requires it. Your own new test shows the cost: <Sources sources={SOURCES} open onOpenChange={() => {}} hideTrigger />, a required callback passed as a no-op purely to satisfy the type. Every caller of this mode writes that same dead prop.
Worth considering: make onOpenChange optional (or split SourcesProps into a union on hideTrigger) so the trigger-less mode doesn't demand a callback it can never invoke.
Separately, a direction question rather than a request: would trigger?: ReactNode, rendered through CollapsibleTrigger asChild, serve #8000 better? The caller's own control would then inherit Base UI's aria-expanded/aria-controls/keyboard wiring instead of having to rebuild it outside the element, and it subsumes hideTrigger (pass nothing, get nothing). hideTrigger is the smaller change, so if you've already weighed this and prefer the boolean, say why and I'm fine with it.

This row is now only conditionally true — with hideTrigger there is no trigger to click, and onOpenChange is never called at all. Since the table gained a hideTrigger row two lines down, this description needs to account for it.

The trigger's count always reads `sources.length`, whether the panel is open or not; an empty `sources` array leaves the trigger reading "0" and the panel opens onto an empty grid or list, depending on `layout`. When a caller already has its own control over `open` (a tab, a sibling toggle) and doesn't want a second, redundant disclosure affordance alongside it, `hideTrigger` renders only the panel content and leaves opening and closing entirely to that caller's own control. `SourceGlyph`, the small domain-initial favicon stand-in shown in both layouts, is exported for a caller building that custom trigger to reuse the same glyph. |

This paragraph tells a caller to reach for hideTrigger, but not what they inherit by doing so. The CollapsibleTrigger is the only thing giving the panel an accessible disclosure relationship (Base UI puts aria-expanded on the trigger and aria-controls pointing at the panel's generated id). Remove it and that id is not exposed anywhere, so a caller's own tab or toggle has no way to reference the panel directly — they need to wrap <Sources hideTrigger /> in their own element and point aria-controls at that, and own aria-expanded themselves.
That's a reasonable trade for a caller taking over the trigger, but it needs to be stated here. "Accessible UI" is a product-contract promise for this catalog, and a reader following this sentence as written ships an orphaned panel without knowing it.

Hide the decorative glyph from assistive technology.
Both layouts render the full domain beside SourceGlyph. The glyph can add a duplicate initial, such as “A assistant-ui.com”. The standalone component is documented and tested as a visual glyph, not as an accessible label.

Fixes #8000.
Draft: blocked on #7962 (branch
sources-trigger-layout, still open). This isn't just two PRs touching the same file: #7962 extracts the domain-glyph markup into its ownSourceGlyphfunction and fixes a key-collision bug (key={source.domain}tokey={index}) as part of adding itslayoutprop, and this PR'shideTriggerchange is written on top of that extraction (it exports the sameSourceGlyph, and its trigger wrapping targets the post-#7962 structure). Rebasing this ontomainas-is produces real conflicts, not a mechanical one. I'll rebase and mark this ready once #7962 merges.What changed
Sources(the source-cards design,elements/sources) always renders its own trigger button.
