Why

The web collection had Select but no field that filters its options as you type. The native collection had Combobox; the web port closes that gap.

What changed

Adds panelui-web/combobox: a text field that filters as you type, with single and multiple values, overlay and inline lists, grouped options, custom values, async loading, clearing, and the value shape tied to the selected mode. Includes the docs page with live demos, the registry item, and the skill reference.

Screenshots and recording

Filtering Grouped options
Combobox with re typed, narrowed to React Native and Remix Combobox list open with Native and Web groups
Several values Custom value
Multiple Combobox with Expo, Remix and Astro chips and the list still open Tag Combobox with a typed platform chip added to design and engineering
Server results Loading
City Combobox showing Toronto after a server-backed search for to City Combobox showing Looking up cities while the server responds
Inline Dark
Inline Combobox with the Remix option expanding under the field Grouped Combobox open in dark mode

Recording of the multiple Combobox: typing rem, choosing Remix, typing as, choosing Astro, and removing the Expo chip

Proof

  • npm test — 1146 contract tests pass
  • npm run typecheck --workspace=panelui-web
  • npm run typecheck --workspace=docs
  • npm run build --workspace=panelui-web
  • npm test --workspace=docs
  • Playwright against the docs page: filtering, grouped filtering, multiple chips, custom values, server-backed loading, inline selection and closing, clearing a controlled undefined value, a focused external value syncing on blur, and the query resetting after a multiple pick

Reviewed with sol-loop: 3 rounds with gpt-6.1-sol. Sol verdict: approved.

Created with DeepSeek V4.1 Flash in T3 Code.

Summary by CodeRabbit

  • New Features
    • Added a Combobox for searching and selecting options, with single or multiple selection, grouped choices, custom values, loading and empty states, and inline or overlay layouts.
    • Added interactive examples covering common Combobox configurations.
  • Documentation
    • Added Combobox guides, API details, examples, and catalogue entries.

Port the native combobox to the web collection. It filters as you type, supports single and multiple selection, overlay and inline lists, grouped options, custom values, loading and cleared states, and keeps the value shape tied to the mode. Document it with live demos, registry and skill entries.

Merge Risk: Low · up to 70fe4

Projects that install the component through the registry CLI with an older Base UI already present may get a Combobox that fails to render. New installs and the in-repo package are unaffected. Before merging, make the registry or CLI require a compatible Base UI version, or document the minimum.

Explanation

The title "feat(web): add Combobox" matches the main change. The changeset adds a new Combobox component to the web package (packages/web/src/components/combobox/index.tsx), with its exports, docs page, registry item, and demos. The title is short and specific. It does not describe every detail, which is expected.

Full details: Docstring Coverage

Explanation

Docstring coverage is 14.29% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 9 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Line 145: Make the grouped and inline Combobox examples safe to copy into

- Line 46: Update the Combobox documentation entry in the web-usage metadata to
set an accurate propsNote for Combobox.Item and Combobox.Group, clarifying that
they accept only their declared props and do not render elements with ordinary
element props. Regenerate the component MDX page and skills through the

Review comments at @packages/web/src/components/combobox/index.tsx:
- Line 612: Remove the input blur calls from both Enter-commit paths in
submitCustom: the exact-match path and the custom-value path. Keep closing the
list and updating the query as currently implemented, while leaving keyboard
focus on the input after commit.
- Around line 420-423: Update labelOf in the combobox to retain labels for
options seen in previous renders and use the cached label when the candidate is
absent from the current options, before falling back to the raw value. Ensure
the retained label is used consistently by the multiple-mode chips,
itemToStringLabel, and the single-mode sync effect that already call labelOf.

Remember option labels once seen so a server-filtered list does not turn a chip or the field into an id. Keep keyboard focus on the input after Enter commits, and make the grouped and inline demos copy-safe as client modules. Correct the docs props note for the declarative parts.

Note

🤖 DeepSeek V4.1 Flash responding on behalf of danestves

Docstring coverage: the functions without docstrings are local JSX helpers (CheckIcon, ChevronDownIcon, XIcon, and Option) plus the already-commented readItems. They are not exported API, and the repository does not document trivial local render helpers; adding prose there would be comment noise rather than coverage. The component, props, option, and group types are documented.

Review comments at @apps/docs/public/r/web/combobox.json:
- Line 20: Update readItems to recursively traverse React fragments so
Combobox.Item elements inside fragments are collected in both the top-level
children path and the Combobox.Group children path. Preserve the existing option
ordering and grouping behavior.
- Line 20: Update the Enter handling in ComboboxRoot so allowCustomValue checks
for an exact option match before committing typed text; if that match is
disabled, return without changing the selection. Preserve custom-value commits
when there is no exact match.
- Line 20: Update the @base-ui/react dependency minimum in the package metadata
and registry installation requirements to 1.8.0 or later, so every installed
version provides BaseCombobox.createItems. Keep the Combobox implementation’s
createItems usage intact.
- Line 20: Update the selection-to-query synchronization in ComboboxRoot to
react when the selected option’s label becomes available or changes, even if
singleValue remains unchanged. Use the current label from the option data to
replace an ID-based internalQuery, while preserving an active user-entered
query; keep the existing value-change behavior intact.
- Line 20: In the Enter-key handler in ComboboxRoot, prevent Base UI from also
handling the event when highlightedExact is committed, using the supported
mechanism for suppressing its handler. This must avoid duplicate value-change
callbacks and prevent an already-selected item from being toggled off, while
preserving submitCustom behavior for unmatched custom values.

Comment thread apps/docs/public/r/web/combobox.json Resolved
danestves and others added 2 commits November 8, 2026 16:07
Walk fragments when reading items, refuse a disabled exact match even with custom values, and update the displayed label when options arrive after the selection. Raise the @base-ui/react floor to the first release with createItems, and stop Base UI handling an Enter that was already committed.
A selected option drew bg-accent under the default foreground text. With the
stock tokens that is only faint; once an app sets accent to a solid colour the
label disappears into it. The check mark now follows the label colour.

Shipped in panelui-web 0.16.0, now on npm. Thanks, @danestves — a thorough port. One fix went in on your branch before the merge: a selected option now pairs bg-accent with text-accent-foreground (and the check follows the label colour), so it stays readable when an app sets accent to a solid colour.
