折叠面板

一套垂直堆叠的可展开区块，用于常见问题解答、设置以及内容丰富的页面——采用新粗野主义风格的边框和阴影处理。

import {
  Accordion,
  AccordionContent,

手风琴把相关内容归拢成垂直堆叠的可展开区块——每个区块一个标题，一次点击即可展开。它基于 Base UI Accordion 组件构建，并按新粗野主义的配方设计：粗边框、硬阴影、加粗字体。

适合以下场景：

  • 常见问题解答——最经典的用法。一次只展开一个问题，答案更容易扫读。
  • 设置与筛选——把不常用的分组折叠起来，又不至于彻底藏住。
  • 内容密集的页面——产品参数、配送说明、更新日志。

更新导入路径以匹配您的项目设置。

用法

import {
  Accordion,
  AccordionContent,
  AccordionItem,
  AccordionTrigger,
} from "@/components/ui/accordion"
<Accordion defaultValue={["item-1"]}>
  <AccordionItem value="item-1">
    <AccordionTrigger>Is it accessible?</AccordionTrigger>
    <AccordionContent>
      Yes. It adheres to the WAI-ARIA design pattern.
    </AccordionContent>
  </AccordionItem>
</Accordion>

组合

使用以下组合来构建 Accordion：

Accordion
├── AccordionItem
│   ├── AccordionTrigger
│   └── AccordionContent
└── AccordionItem
    ├── AccordionTrigger
    └── AccordionContent

示例

基础

一次只显示一个项目的基础手风琴。第一个项目默认展开。

import {
  Accordion,
  AccordionContent,

多选

使用 multiple 属性可以让多个项目同时展开。

import {
  Accordion,
  AccordionContent,

禁用

在 AccordionItem 上使用 disabled 属性可以禁用单个项目。

import {
  Accordion,
  AccordionContent,

边框

在 Accordion 上添加 border，并在 AccordionItem 上添加 border-b last:border-b-0，即可为各个项目添加边框。

import {
  Accordion,
  AccordionContent,

卡片

将 Accordion 包裹在 Card 组件中。

import {
  Accordion,
  AccordionContent,

RTL

要在 Neobrutalism 中启用 RTL 支持，请参阅 RTL 配置指南。

"use client"

import * as React from "react"

无障碍

手风琴遵循 WAI-ARIA Accordion 模式：触发器都是真正的按钮，并接好了 aria-expanded 和 aria-controls，因此屏幕阅读器会读出每个区块及其状态。

键盘交互：

按键操作
Tab / Shift + Tab在各触发器之间移动焦点，或移出手风琴
Space / Enter展开或收起当前聚焦的区块
ArrowDown / ArrowUp把焦点移到下一个或上一个触发器
Home / End跳到第一个或最后一个触发器
