Merge Risk: 🟡 Moderate · up to 5b579

The new Slider wrappers can fail type validation or lose consumer-provided state-based styling. The example also needs its accessibility label localized according to the desktop UI contract before merge.

site:base-ui.com/react/components/slider Base UI Slider className function state

💡 Result:

<search_synthesis>
In Base UI, the className prop for components such as the Slider accepts either a string or a function [1]. When provided as a function, it receives the component&#39;s internal state as an argument, allowing you to dynamically apply CSS classes based on that state [1]. The type signature for the className prop is: string | ((state: Slider.Root.State) => string | undefined) | undefined [1]. This pattern is available across various Slider sub-components, including the Root, Track, and Thumb, enabling custom styling based on the specific state of those elements [1].

각 Slider 래퍼에서 함수형 className을 보존하세요.

SliderTrack, SliderIndicator, SliderThumb, SliderControl은 Base UI의 string | ((state) => string | undefined) 계약을 지원합니다. 그러나 cnclsxClassValue만 허용하므로 현재 코드는 타입 검사를 통과하지 못합니다. 검사를 우회하면 clsx가 함수 값을 무시하여 호출자 스타일을 잃습니다. Slider와 같은 조건부 상태 함수로 네 래퍼의 className을 감싸세요.

-      className={cn("relative h-2 w-full grow overflow-hidden rounded-full bg-secondary", className)}
+      className={
+        typeof className === "function"
+          ? (state) =>
+              cn(
+                "relative h-2 w-full grow overflow-hidden rounded-full bg-secondary",

+              className

+      }

동일한 처리를 SliderIndicator, SliderThumb, SliderControl에도 적용하세요.

이 PR은 독립 Slider source owner로 취급하지 않습니다. Live exact head 5b579b222c4fa2dc93ebf0a2574f813e5d4b9c12를 확인한 결과 변경 5개 중 services/analysis-engine/tests/test_supply_chain_policy.py#1176 exact 8fe6b6d99c009527ef0bcba419e6f6debdb23c23의 formatter-only delta와 byte-for-byte 같은 foreign-owner 변경입니다.

Slider 자체의 canonical owner는 Draft #1188 exact a936b9d0ab91d52fe45323e449a47ff1df03fa63입니다. #1188은 이 PR의 Root/Control/Track/Indicator/Thumb primitive와 기본 Storybook/render test를 포함하면서, range의 named multi-thumb, vertical composition, disabled state, RTL keyboard semantics, Track overflow 제거, extended thumb target regression, dependency/lockfile 및 doctoring evidence까지 더 강한 contract로 소유합니다. 특히 이 PR의 SliderTrackoverflow-hidden을 두고 있어 range thumb/collision acceptance 방향과 맞지 않습니다.

따라서 Ready 상태는 잘못된 owner admission으로 보고 Draft로 되돌렸습니다. 현재는 preservation/consolidation lane입니다. #1188에서 이 PR의 유효 source/test/story/CHANGELOG delta가 모두 보존됐는지 exact tree로 마지막 확인한 뒤에만 unmerged close 후보가 됩니다. #1176 formatter delta를 여기서 merge하거나 복제하지 않습니다. No self-approval, bypass, no-op retrigger, force-push, destructive rebase or gate weakening.
