as optional and only an optimization in both item-collection sections. State
that Highlight responds to changes in text or query, while emphasizing that each
collection must use the current query when deriving its values.
In `@packages/components/src/components/SelectNext/Select.mdx`:
- Around line 197-203: Restore the complete dependencies guidance near the
Highlighting matches example, covering Select.dependencies’ fixed-length
requirement, inherited dependencies for Select.Section content, and the need for
Select.items-rendered sections to list values on Select while JSX sections may
add their own dependencies. Alternatively, link clearly to the existing
Dependencies section.

- Line 1: Add the 'use client' directive before imports in both
Select.stories.tsx and TreeSelect.stories.tsx, following the repository
convention for component TSX files.
In `@packages/components/src/components/TreeSelect/TreeSelect.mdx`:
- Around line 159-160: Update the TreeSelect documentation around
Tree.ItemContentText to state that dependencies must always have a constant
length, wrapping lists as a single dependency such as dependencies={[filters]};
also note that nested Collection elements inherit the root dependencies.

🟢 Approval recommended
The change is documentation and Storybook examples only, and all referenced slots, props, and story references were verified to exist and be used correctly with no dangling references.
Pull request overview
This PR is a documentation/stories update that replaces the abstract "Dependencies" caching examples with concrete "Highlighting matches" examples across five collection-based components. It demonstrates how to use the Highlight component inside each component's text slot so matched query text is highlighted as the user types, and documents the two mechanisms that keep the highlight in sync with the query (passing the query in dependencies for statically-fed collections, or rebuilding the filtered list in useMemo for pre-filtered collections).
Changes:
- Added
HighlightingMatchesstories forDropdownMenu,SelectNext,TagAutocomplete, andTreeSelect, and refactored the existingAutocompleteexample to wrapHighlightin the item text slot. - Removed the previous
Dependenciesstories/sections fromSelectNextandTreeSelect, replacing them with focused highlighting documentation. - Updated each component's MDX to add a "Highlighting matches" section pointing at the new story.

There was a problem hiding this comment.
inputValue={inputValue} makes the search input controlled, and that silently disables Select's own reset-on-close: the effect in SelectInner bails out when inputValueProp !== undefined, so the query is never cleared after the dropdown closes.
Verified in Storybook: open, type att, close, reopen → the search box still holds att and the list is still filtered to 3 options. The uncontrolled Searchable story reopens with an empty query and all 11 options.
Nothing here needs the controlled value — onInputChange already feeds both Highlight and dependencies, and the prose above the story only mentions dependencies.

Fixed — dropped inputValue, onInputChange alone feeds Highlight and dependencies. Reopening now starts empty with all 6 options.
The controlled mode itself still skips the reset, so that part is DS-5576.

Same problem as in the Select example: making the query controlled disables TreeSelect's reset-on-close, which is guarded by inputValueProp !== undefined in TreeSelectInner.
Verified in Storybook: open, type app, dismiss by clicking outside, reopen → the search box still holds app, the tree is still filtered to app / app.js, and the old matches are still highlighted.
onInputChange alone is enough for Highlight and dependencies.

Here the controlled inputValue is genuinely needed (it feeds Highlight and dependencies), but nothing ever resets it, so the query outlives the popover. Uncontrolled, RAC's Autocomplete state is thrown away when DropdownMenu.Popover unmounts.
Verified in Storybook: open, type bu, dismiss by clicking outside, reopen → the search box still holds bu and the menu is still filtered to Bucharest / Budapest. The existing uncontrolled Search story reopens empty with all 22 items.
Clearing the query when the menu closes keeps the example faithful to the default behaviour — e.g. <DropdownMenu {...args} onOpenChange={(isOpen) => { if (!isOpen) setInputValue(''); }}>.

Fixed with your onOpenChange reset. Reopening shows all 8 cities and an empty search box.
The component doing this on its own is DS-5576 — once it lands, the manual reset comes out of this story.

There was a problem hiding this comment.
This rule is stated in terms of the wrong mechanism, and a reader following it literally will still get a stale highlight.
CollectionBuilder caches a rendered node by the identity of the item object (this.cache.get(partialNode.value) in @react-stately/collections), and Autocomplete has no dependencies escape hatch. The story works because the object literals are created inside the useMemo, so every keystroke produces brand-new objects — not because the memo is keyed by the query.
Written the way this sentence reads, it silently breaks:
const PROTOCOLS = [{ key: 'tls', name: 'TLS' }, /* … */];
// useMemo keyed by the query, yet the highlight never updates:
// the surviving objects are cache hits.
const items = useMemo(
() => PROTOCOLS.filter((item) => contains(item.name, inputValue)),
[contains, inputValue]
);Worth saying what actually matters — the item objects have to be new when the query changes (which also means the pre-PR version of this story, which rebuilt the array on every render, was not broken either). The same sentence appears in TagAutocomplete.mdx.

You're right, rewrote it: the options have to be new objects when the query changes, and filtering a constant array reuses them.

There was a problem hiding this comment.
Same wording problem as in Autocomplete.mdx: it is not the useMemo that makes the highlight update, it is the fact that the suggestion objects are re-created inside it. useTagAutocompleteState → useListState → CollectionBuilder caches each rendered node by item-object identity, so useMemo(() => SUGGESTIONS.filter(…), [inputValue]) over a stable module-level array is keyed by the query and still renders a stale highlight.

Rewritten the same way.

The rewrite drops the textValue half of the old paragraph ("set textValue on the item so the collection keeps a plain-text label for typeahead and accessibility"), and none of the four new sections in this PR mention it either.
It is load-bearing in every one of the five examples: once the item's children are a <Highlight> element instead of a string, textValue is the only source for filtering, typeahead and the option's accessible name. A reader who copies the snippet without it gets a list that stops filtering and an option with no accessible label — a silent failure, not a type error.

Restored, and added to all five sections — it is load-bearing in each of them.

| ### Highlighting matches |
There was a problem hiding this comment.
This replaces, rather than complements, the ### Dependencies section — and dependencies shipped only one commit earlier (2b51a4a, #475). Two things that had no other home are now gone from the docs:
Select.Sectioninheritsdependenciesfrom the root, so the prop only has to be set once — and a JSX section can carry its owndependencies. Nothing in the generated Props table says this.- The
Dependenciesstory was the only worked example of the prop.
Highlighting is the motivating case, not the whole feature (dependencies matters for any value read inside the render function). Keeping both sections — Dependencies for the mechanism, Highlighting matches for the recipe — seems better than folding the mechanism into a single half-sentence.
There was a problem hiding this comment.
We're keeping the section folded for now. Describing the caching mechanism once, in a shared place, rather than per component page is part of DS-5529 — which also adds dependencies to Autocomplete and TagAutocomplete.

Same as in Select.mdx: the ### Dependencies section is deleted outright, one commit after the prop was added (2b51a4a, #475). The note it carried — "Nested Collection elements inherit dependencies from the TreeSelect, so the prop only has to be set once, on the root" — is not stated anywhere else, and it is exactly the question a reader of the new story will have, since the story renders <Collection items={item.children}> without dependencies.

Same answer as in Select.mdx — DS-5529.

There was a problem hiding this comment.
Tree.ItemContentText is not a slot of TreeSelect — the compound only assigns Item, ItemContent, LoadMoreItem and Tag (TreeSelect.tsx), so a consumer following this page has to import Tree as well, on a page that otherwise says TreeSelect.Item / TreeSelect.ItemContent.
Select handles the equivalent case by exposing Select.ItemText. Adding ItemContentText (and ItemContentAddon, which is in the same position) to the TreeSelect compound would let this read TreeSelect.ItemContentText and let the slot appear in meta.subcomponents, which AGENTS.md asks for ("Add every slot of a compound component to meta.subcomponents").
There was a problem hiding this comment.
Agreed. DS-5575: add TreeSelect.ItemContentText and TreeSelect.ItemContentAddon to the compound, with meta.subcomponents and an API report update. Out of scope for a docs PR since it changes the public API.

Passing the pre-filtered list as items (rather than defaultItems) hands the collection over to the story, and useComboBoxState reacts by turning its own machinery off:
// react-stately/combobox
let filteredCollection = useMemo(() => (
// No default filter if items are controlled.
props.items != null || !defaultFilter ? triggerState.collection : filterCollection(...)
), [...]);Two consequences the MDX doesn't mention:
defaultFilter(and thecontainsdefault documented in "Custom filtering") is dead on this example — filtering is entirely the story's job.- "Show all options" on a manual open is gone.
showAllItemsfalls back tooriginalCollection, which here is the filtered list, so opening the dropdown with the chevron while the input holdsssstill shows only SSH instead of all five protocols.
Neither is avoidable with today's API — Autocomplete has no dependencies prop, so pre-filtering is the only way to get fresh item identities. Worth at least calling the trade-off out in the section, so readers don't copy it into a case where the chevron behaviour matters.
There was a problem hiding this comment.
Called out in the section now: defaultFilter is not called and the chevron opens the filtered list instead of all options. The workaround itself goes away with DS-5529.

This is the only story in the file that filters by hand instead of passing defaultFilter={containsFilter} — and it re-implements what useTagAutocompleteState's built-in filter already does. It also contradicts the "Suggestions" section two paragraphs above the new one, which tells the reader that "defaultFilter(textValue, inputValue) filters the popover list".
The manual filter isn't what makes the highlight work — fresh item identities are. Both can be had by just building the array inside render and letting the component filter:
| const suggestions = useMemo( | |
| () => | |
| [ | |
| { id: 'react', name: 'React' }, | |
| { id: 'typescript', name: 'TypeScript' }, | |
| { id: 'storybook', name: 'Storybook' }, | |
| { id: 'vite', name: 'Vite' }, | |
| { id: 'vitest', name: 'Vitest' }, | |
| { id: 'playwright', name: 'Playwright' }, | |
| ].filter((item) => containsFilter(item.name, inputValue)), | |
| [inputValue] | |
| ); | |
| const suggestions = [ | |
| { id: 'react', name: 'React' }, | |
| { id: 'typescript', name: 'TypeScript' }, | |
| { id: 'storybook', name: 'Storybook' }, | |
| { id: 'vite', name: 'Vite' }, | |
| { id: 'vitest', name: 'Vitest' }, | |
| { id: 'playwright', name: 'Playwright' }, | |
| ]; |
…with defaultFilter={containsFilter} back on the component (and useMemo dropped from the import).

Fixed — took your suggestion: the array is built inside render and defaultFilter={containsFilter} is back.

Stepping back from this one story: the PR ends up documenting two different answers to the same question.
Select,TreeSelectandDropdownMenu.Contenttakedependencies, so their examples keep a stableuseMemo(…, [])list and declare the query — the shape the docs already teach.AutocompleteandTagAutocompletehave no such prop, so their examples have to churn item identities on every keystroke. That workaround is more fragile (it breaks the moment someone hoists the source array — see the.mdxcomment), it throws away memoization, and forAutocompleteit also forcesitemsoverdefaultItems, which disables the component's own filtering.
The deeper fix is to give Autocomplete and TagAutocomplete a dependencies prop too — they build their collections through useCollection/CollectionBuilder, whose cache is exactly what dependencies invalidates — and then all five pages say the same thing. Reasonable to land these examples first and follow up, but worth a ticket rather than leaving the second idiom as documented guidance.
There was a problem hiding this comment.
Agreed, filed as DS-5529: dependencies for Autocomplete and TagAutocomplete, then all five pages say the same thing. Landing the examples first.
