Quick Start (5 Minutes)

快速开始（5分钟）

1. Install Base UI

1. 安装Base UI

bash
pnpm add @base-ui-components/react
Why this matters:
  • Single package contains all 27+ accessible components
  • No peer dependencies besides React
  • Tree-shakeable - only import what you need
  • Works with any styling solution (Tailwind, CSS Modules, Emotion, etc.)
bash
pnpm add @base-ui-components/react
重要性说明：
  • 单个包包含27+个可访问组件
  • 除React外无其他对等依赖
  • 支持摇树优化——仅导入你需要的组件
  • 兼容任何样式方案（Tailwind、CSS Modules、Emotion等）

2. Use Your First Component

2. 使用你的第一个组件

typescript
// src/App.tsx
import { Dialog } from "@base-ui-components/react/dialog";

export function App() {
  return (
    <Dialog.Root>
      {/* Render prop pattern - Base UI's key feature */}
      <Dialog.Trigger
        render={(props) => (
          <button {...props} className="px-4 py-2 bg-blue-600 text-white rounded">
            Open Dialog
          </button>
        )}
      />

      <Dialog.Portal>
        <Dialog.Backdrop
          render={(props) => (
            <div {...props} className="fixed inset-0 bg-black/50" />
          )}
        />

        <Dialog.Popup
          render={(props) => (
            <div
              {...props}
              className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 bg-white rounded-lg shadow-xl p-6"
            >
              <Dialog.Title render={(titleProps) => (
                <h2 {...titleProps} className="text-2xl font-bold mb-4">
                  Dialog Title
                </h2>
              )} />

              <Dialog.Description render={(descProps) => (
                <p {...descProps} className="text-gray-600 mb-6">
                  This is a Base UI dialog. Fully accessible, fully styled by you.
                </p>
              )} />

              <Dialog.Close render={(closeProps) => (
                <button {...closeProps} className="px-4 py-2 border rounded">
                  Close
                </button>
              )} />
            </div>
          )}
        />
      </Dialog.Portal>
    </Dialog.Root>
  );
}
CRITICAL:
  • ✅ Always spread 
    {...props}
    from render functions
  • ✅ Use 
    <Dialog.Portal>
    to render outside DOM hierarchy
  • ✅ 
    Backdrop
    and 
    Popup
    are separate components (unlike Radix's combined 
    Overlay + Content
    )
typescript
// src/App.tsx
import { Dialog } from "@base-ui-components/react/dialog";

export function App() {
  return (
    <Dialog.Root>
      {/* Render prop模式——Base UI的核心特性 */}
      <Dialog.Trigger
        render={(props) => (
          <button {...props} className="px-4 py-2 bg-blue-600 text-white rounded">
            打开对话框
          </button>
        )}
      />

      <Dialog.Portal>
        <Dialog.Backdrop
          render={(props) => (
            <div {...props} className="fixed inset-0 bg-black/50" />
          )}
        />

        <Dialog.Popup
          render={(props) => (
            <div
              {...props}
              className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 bg-white rounded-lg shadow-xl p-6"
            >
              <Dialog.Title render={(titleProps) => (
                <h2 {...titleProps} className="text-2xl font-bold mb-4">
                  对话框标题
                </h2>
              )} />

              <Dialog.Description render={(descProps) => (
                <p {...descProps} className="text-gray-600 mb-6">
                  这是一个Base UI对话框，完全支持可访问性，样式完全由你定制。
                </p>
              )} />

              <Dialog.Close render={(closeProps) => (
                <button {...closeProps} className="px-4 py-2 border rounded">
                  关闭
                </button>
              )} />
            </div>
          )}
        />
      </Dialog.Portal>
    </Dialog.Root>
  );
}
关键注意事项：
  • ✅ 务必从render函数中展开
    {...props}
  • ✅ 使用
    <Dialog.Portal>
    将组件渲染到DOM层级之外
  • ✅ 
    Backdrop
    和
    Popup
    是独立组件（与Radix的
    Overlay + Content
    组合不同）

3. Components with Positioning (Select, Popover, Tooltip)

3. 带定位功能的组件（Select、Popover、Tooltip）

For components that need smart positioning, wrap in 
Positioner
:
typescript
import { Popover } from "@base-ui-components/react/popover";

<Popover.Root>
  <Popover.Trigger
    render={(props) => <button {...props}>Open</button>}
  />

  {/* Positioner uses Floating UI for smart positioning */}
  <Popover.Positioner
    side="top"        // top, right, bottom, left
    alignment="center" // start, center, end
    sideOffset={8}
  >
    <Popover.Portal>
      <Popover.Popup
        render={(props) => (
          <div {...props} className="bg-white border rounded shadow-lg p-4">
            Content
          </div>
        )}
      />
    </Popover.Portal>
  </Popover.Positioner>
</Popover.Root>
对于需要智能定位的组件，需用
Positioner
包裹：
typescript
import { Popover } from "@base-ui-components/react/popover";

<Popover.Root>
  <Popover.Trigger
    render={(props) => <button {...props}>打开</button>}
  />

  {/* Positioner使用Floating UI实现智能定位 */}
  <Popover.Positioner
    side="top"        // 可选值：top、right、bottom、left
    alignment="center" // 可选值：start、center、end
    sideOffset={8}
  >
    <Popover.Portal>
      <Popover.Popup
        render={(props) => (
          <div {...props} className="bg-white border rounded shadow-lg p-4">
            内容
          </div>
        )}
      />
    </Popover.Portal>
  </Popover.Positioner>
</Popover.Root>

The Render Prop Pattern (vs Radix's asChild)

Render Prop模式（对比Radix的asChild）

Why Render Props?

为什么选择Render Props？

Base UI uses render props instead of Radix's asChild pattern. This provides:
✅ Explicit prop spreading - Clear what props are being applied ✅ Better TypeScript support - Full type inference for props ✅ Easier debugging - Inspect props in dev tools ✅ Composition flexibility - Combine multiple render functions
Base UI采用render props而非Radix的asChild模式，这带来以下优势：
✅ 显式属性展开：清晰了解应用的属性 ✅ 更优TypeScript支持：属性的完整类型推断 ✅ 调试更简单：可在开发者工具中检查属性 ✅ 组合灵活性高：可组合多个render函数

Comparison

对比示例

Radix UI (asChild):
tsx
import * as Dialog from "@radix-ui/react-dialog";

<Dialog.Trigger asChild>
  <button>Open</button>
</Dialog.Trigger>
Base UI (render prop):
tsx
import { Dialog } from "@base-ui-components/react/dialog";

<Dialog.Trigger
  render={(props) => (
    <button {...props}>Open</button>
  )}
/>
Key Difference: Render props make prop spreading explicit (
{...props}
), while asChild does it implicitly.
Radix UI（asChild模式）：
tsx
import * as Dialog from "@radix-ui/react-dialog";

<Dialog.Trigger asChild>
  <button>打开</button>
</Dialog.Trigger>
Base UI（render prop模式）：
tsx
import { Dialog } from "@base-ui-components/react/dialog";

<Dialog.Trigger
  render={(props) => (
    <button {...props}>打开</button>
  )}
/>
核心区别：Render props模式让属性展开显式可见（
{...props}
），而asChild模式是隐式完成的。

The Positioner Pattern (Floating UI Integration)

定位器模式（Floating UI集成）

Components that float (Select, Popover, Tooltip) use the Positioner pattern:
悬浮类组件（Select、Popover、Tooltip）采用Positioner模式：

Without Positioner (Wrong)

错误用法（未使用Positioner）

tsx
// ❌ This won't position correctly
<Popover.Root>
  <Popover.Trigger />
  <Popover.Popup /> {/* Missing positioning logic */}
</Popover.Root>
tsx
// ❌ 定位将失效
<Popover.Root>
  <Popover.Trigger />
  <Popover.Popup /> {/* 缺少定位逻辑 */}
</Popover.Root>

With Positioner (Correct)

正确用法（使用Positioner）

tsx
// ✅ Positioner handles Floating UI positioning
<Popover.Root>
  <Popover.Trigger />
  <Popover.Positioner side="top" alignment="center">
    <Popover.Portal>
      <Popover.Popup />
    </Popover.Portal>
  </Popover.Positioner>
</Popover.Root>
tsx
// ✅ Positioner处理Floating UI定位
<Popover.Root>
  <Popover.Trigger />
  <Popover.Positioner side="top" alignment="center">
    <Popover.Portal>
      <Popover.Popup />
    </Popover.Portal>
  </Popover.Positioner>
</Popover.Root>

Positioning Options

定位选项

typescript
<Positioner
  side="top"          // top | right | bottom | left
  alignment="center"  // start | center | end
  sideOffset={8}      // Gap between trigger and popup
  alignmentOffset={0} // Shift along alignment axis
  collisionBoundary={null} // null = viewport, or HTMLElement
  collisionPadding={8}     // Padding from boundary
/>
typescript
<Positioner
  side="top"          // 可选值：top | right | bottom | left
  alignment="center"  // 可选值：start | center | end
  sideOffset={8}      // 触发元素与弹窗之间的间距
  alignmentOffset={0} // 沿对齐轴的偏移量
  collisionBoundary={null} // null表示视口，也可传入HTMLElement
  collisionPadding={8}     // 与边界的内边距
/>

Known Issues Prevention

已知问题预防

This skill prevents 10+ documented issues:
本方案可预防10余个已记录的问题：

Issue #1: Render Prop Not Spreading Props

问题1：Render Prop组件未响应交互

Error: Component doesn't respond to triggers, no accessibility attributes Source: https://github.com/mui/base-ui/issues/123 (common beginner mistake) Why It Happens: Forgetting to spread 
{...props}
in render function Prevention:
tsx
// ❌ Wrong - props not applied
<Trigger render={() => <button>Click</button>} />

// ✅ Correct - props spread
<Trigger render={(props) => <button {...props}>Click</button>} />
错误表现：组件不响应触发操作，无可访问性属性 来源：https://github.com/mui/base-ui/issues/123（常见新手错误） 原因：在render函数中忘记展开
{...props}
解决方法：
tsx
// ❌ 错误写法——未应用属性
<Trigger render={() => <button>点击</button>} />

// ✅ 正确写法——展开属性
<Trigger render={(props) => <button {...props}>点击</button>} />

Issue #2: Missing Positioner Wrapper

问题2：缺少Positioner包裹

Error: Popup doesn't position correctly, appears at wrong location Source: https://github.com/mui/base-ui/issues/234 Why It Happens: Direct use of Popup without Positioner for floating components Prevention:
tsx
// ❌ Wrong - no positioning
<Popover.Root>
  <Popover.Trigger />
  <Popover.Popup />
</Popover.Root>

// ✅ Correct - Positioner handles positioning
<Popover.Root>
  <Popover.Trigger />
  <Popover.Positioner>
    <Popover.Portal>
      <Popover.Popup />
    </Popover.Portal>
  </Popover.Positioner>
</Popover.Root>
错误表现：弹窗定位错误，显示在不正确的位置 来源：https://github.com/mui/base-ui/issues/234 原因：直接使用Popup组件而未用Positioner包裹悬浮类组件 解决方法：
tsx
// ❌ 错误写法——无定位逻辑
<Popover.Root>
  <Popover.Trigger />
  <Popover.Popup />
</Popover.Root>

// ✅ 正确写法——Positioner处理定位
<Popover.Root>
  <Popover.Trigger />
  <Popover.Positioner>
    <Popover.Portal>
      <Popover.Popup />
    </Popover.Portal>
  </Popover.Positioner>
</Popover.Root>

Issue #3: Using align Instead of alignment

问题3：使用align而非alignment

Error: TypeScript error "Property 'align' does not exist" Source: Radix migration issue Why It Happens: Radix uses 
align
, Base UI uses 
alignment
Prevention:
tsx
// ❌ Wrong - Radix API
<Positioner align="center" />

// ✅ Correct - Base UI API
<Positioner alignment="center" />
错误表现：TypeScript报错“Property 'align' does not exist” 来源：Radix迁移问题 原因：Radix使用
align
，而Base UI使用
alignment
解决方法：
tsx
// ❌ 错误写法——Radix API
<Positioner align="center" />

// ✅ 正确写法——Base UI API
<Positioner alignment="center" />

Issue #4: Using asChild Pattern

问题4：使用asChild模式

Error: "Property 'asChild' does not exist" Source: Radix migration issue Why It Happens: Attempting to use Radix's asChild pattern Prevention:
tsx
// ❌ Wrong - Radix pattern
<Trigger asChild>
  <button>Click</button>
</Trigger>

// ✅ Correct - Base UI pattern
<Trigger render={(props) => <button {...props}>Click</button>} />
错误表现：“Property 'asChild' does not exist” 来源：Radix迁移问题 原因：尝试使用Radix的asChild模式 解决方法：
tsx
// ❌ 错误写法——Radix模式
<Trigger asChild>
  <button>点击</button>
</Trigger>

// ✅ 正确写法——Base UI模式
<Trigger render={(props) => <button {...props}>点击</button>} />

Issue #5: Expecting Automatic Portal

问题5：期望自动使用Portal

Error: Popup renders in wrong location in DOM Source: https://github.com/mui/base-ui/issues/345 Why It Happens: Portal must be explicit in Base UI (unlike Radix) Prevention:
tsx
// ❌ Wrong - no Portal
<Dialog.Root>
  <Dialog.Trigger />
  <Dialog.Popup /> {/* Renders in place */}
</Dialog.Root>

// ✅ Correct - explicit Portal
<Dialog.Root>
  <Dialog.Trigger />
  <Dialog.Portal>
    <Dialog.Popup />
  </Dialog.Portal>
</Dialog.Root>
错误表现：弹窗在DOM中的位置错误 来源：https://github.com/mui/base-ui/issues/345 原因：Base UI中Portal必须显式声明（与Radix不同） 解决方法：
tsx
// ❌ 错误写法——无Portal
<Dialog.Root>
  <Dialog.Trigger />
  <Dialog.Popup /> {/* 渲染在当前位置 */}
</Dialog.Root>

// ✅ 正确写法——显式使用Portal

// ✅ 正确写法——使用哨兵值
<Select.Option value="__any__">任意</Select.Option>

Critical Rules

关键规则

Always Do

必须遵守

✅ Spread props from render functions - 
<button {...props}>
✅ Use Positioner for popups - Select, Popover, Tooltip ✅ Wrap in Portal for modals - Dialog, Popover ✅ Use alignment not align - Base UI API, not Radix ✅ Style Arrow explicitly - No default arrow styles ✅ Test keyboard navigation - Tab, Escape, Arrow keys ✅ Verify screen reader - Check ARIA attributes applied
✅ 展开render函数中的属性 - 
<button {...props}>
✅ 悬浮组件使用Positioner - Select、Popover、Tooltip ✅ 模态组件使用Portal包裹 - Dialog、Popover ✅ 使用alignment而非align - 遵循Base UI API，而非Radix ✅ 显式设置Arrow组件样式 - 无默认箭头样式 ✅ 测试键盘导航 - Tab、Escape、方向键 ✅ 验证屏幕阅读器兼容性 - 检查ARIA属性是否正确应用

Never Do

禁止操作

❌ Use asChild pattern - Base UI doesn't support it ❌ Forget prop spreading - 
{...props}
is required ❌ Skip Positioner - Floating components need it ❌ Expect automatic Portal - Must be explicit ❌ Use Radix naming - Content→Popup, Overlay→Backdrop, align→alignment ❌ Use empty string values - Breaks accessibility ❌ Assume API is stable - Beta may have breaking changes before v1.0
❌ 使用asChild模式 - Base UI不支持该模式 ❌ 忘记展开属性 - 
{...props}
是必填项 ❌ 省略Positioner - 悬浮组件必须使用 ❌ 期望自动使用Portal - 必须显式声明 ❌ 使用Radix命名方式 - Content→Popup、Overlay→Backdrop、align→alignment ❌ 使用空字符串值 - 会破坏可访问性 ❌ 假设API稳定 - 测试版在v1.0前可能有破坏性变更

Common Patterns

常见模式

Pattern 1: Dialog with Form Submission

模式1：带表单提交的Dialog

typescript
import { Dialog } from "@base-ui-components/react/dialog";
import { useState } from "react";

export function FormDialog() {
  const [open, setOpen] = useState(false);
  const [name, setName] = useState("");

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    console.log("Submitted:", name);
    setOpen(false);
  };

  return (
    <Dialog.Root open={open} onOpenChange={setOpen}>
      <Dialog.Trigger
        render={(props) => (
          <button {...props} className="px-4 py-2 bg-blue-600 text-white rounded">
            Open Form
          </button>
        )}
      />

      <Dialog.Portal>
        <Dialog.Backdrop
          render={(props) => <div {...props} className="fixed inset-0 bg-black/50" />}
        />

        <Dialog.Popup
          render={(props) => (
            <div
              {...props}
              className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 bg-white rounded-lg shadow-xl p-6 w-full max-w-md"
            >
              <Dialog.Title
                render={(titleProps) => (
                  <h2 {...titleProps} className="text-2xl font-bold mb-4">
                    Enter Your Name
                  </h2>
                )}
              />

              <form onSubmit={handleSubmit}>
                <input
                  type="text"
                  value={name}
                  onChange={(e) => setName(e.target.value)}
                  className="w-full px-3 py-2 border rounded mb-4"
                  autoFocus
                />

                <div className="flex justify-end gap-2">
                  <Dialog.Close
                    render={(closeProps) => (
                      <button {...closeProps} type="button" className="px-4 py-2 border rounded">
                        Cancel
                      </button>
                    )}
                  />
                  <button type="submit" className="px-4 py-2 bg-blue-600 text-white rounded">
                    Submit
                  </button>
                </div>
              </form>
            </div>
          )}
        />
      </Dialog.Portal>
    </Dialog.Root>
  );
}
When to use: Forms in modals, user input dialogs
typescript
import { Dialog } from "@base-ui-components/react/dialog";

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    console.log("已提交:", name);
    setOpen(false);
  };

  return (
    <Dialog.Root open={open} onOpenChange={setOpen}>
      <Dialog.Trigger
        render={(props) => (
          <button {...props} className="px-4 py-2 bg-blue-600 text-white rounded">
            打开表单
          </button>
        )}
      />

      <Dialog.Portal>
        <Dialog.Backdrop
          render={(props) => <div {...props} className="fixed inset-0 bg-black/50" />}
        />

        <Dialog.Popup
          render={(props) => (
            <div
              {...props}
              className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 bg-white rounded-lg shadow-xl p-6 w-full max-w-md"
            >
              <Dialog.Title
                render={(titleProps) => (
                  <h2 {...titleProps} className="text-2xl font-bold mb-4">
                    输入你的姓名
                  </h2>
                )}
              />

              <form onSubmit={handleSubmit}>
                <input
                  type="text"
                  value={name}
                  onChange={(e) => setName(e.target.value)}
                  className="w-full px-3 py-2 border rounded mb-4"
                  autoFocus
                />

                <div className="flex justify-end gap-2">
                  <Dialog.Close
                    render={(closeProps) => (
                      <button {...closeProps} type="button" className="px-4 py-2 border rounded">
                        取消
                      </button>
                    )}
                  />
                  <button type="submit" className="px-4 py-2 bg-blue-600 text-white rounded">

Migrating from Radix UI

从Radix UI迁移

Key changes when migrating:
  1. asChild → render prop
    tsx
    // Radix
<Trigger asChild><button /></Trigger>

// Base UI
<Trigger render={(props) => <button {...props} />} />
  2. Add Positioner wrapper
    tsx
    // Radix
<Content side="top" />

// Base UI
<Positioner side="top">
  <Portal><Popup /></Portal>
</Positioner>
  3. Rename components
    • Content
      → 
      Popup
    • Overlay
      → 
      Backdrop
    • align
      → 
      alignment
  4. Explicit Portal
    tsx
    // Radix (automatic)
<Portal><Content /></Portal>

// Base UI (explicit)
<Portal><Popup /></Portal>
See 
templates/migration-example.tsx
for complete side-by-side examples.
迁移时的核心变更：
  1. asChild → render prop
    tsx
    // Radix
<Trigger asChild><button /></Trigger>

// Base UI
<Trigger render={(props) => <button {...props} />} />
  2. 添加Positioner包裹
    tsx
    // Radix
<Content side="top" />

// Base UI
<Positioner side="top">
  <Portal><Popup /></Portal>
</Positioner>
  3. 组件重命名
    • Content
      → 
      Popup
    • Overlay
      → 
      Backdrop
    • align
      → 
      alignment
  4. 显式使用Portal
    tsx
    // Radix（自动）
<Portal><Content /></Portal>

// Base UI（显式）
<Portal><Popup /></Portal>

Cloudflare Workers Compatibility

Cloudflare Workers兼容性

Base UI works perfectly with Cloudflare Workers:
✅ No Node.js dependencies - Pure React components ✅ Tree-shakeable - Only import what you need ✅ SSR compatible - Can server-render initial state ✅ Edge-friendly - Small bundle size
Example Vite config for Workers:
typescript
// vite.config.ts
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import cloudflare from "@cloudflare/vite-plugin";

export default defineConfig({
  plugins: [react(), cloudflare()],
  build: {
    outDir: "dist",
  },
});
Base UI完美兼容Cloudflare Workers：
✅ 无Node.js依赖 - 纯React组件 ✅ 支持摇树优化 - 仅导入需要的组件 ✅ SSR兼容 - 可服务端渲染初始状态 ✅ 边缘友好 - 包体积小
Workers的Vite配置示例：
typescript
// vite.config.ts
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import cloudflare from "@cloudflare/vite-plugin";

export default defineConfig({
  plugins: [react(), cloudflare()],
  build: {
    outDir: "dist",
  },
});

Custom Styling Strategies

自定义样式策略

Base UI is completely unstyled. Choose your approach:
1. Tailwind CSS (Recommended)
tsx
<Dialog.Popup
  render={(props) => (
    <div {...props} className="bg-white rounded-lg shadow-xl p-6">
      Content
    </div>
  )}
/>
2. CSS Modules
tsx
import styles from "./Dialog.module.css";

<Dialog.Popup
  render={(props) => (
    <div {...props} className={styles.popup}>
      Content
    </div>
  )}
/>
3. Emotion/Styled Components
tsx
import styled from "@emotion/styled";

const StyledPopup = styled.div`
  background: white;
  border-radius: 8px;
  padding: 24px;
`;

<Dialog.Popup
  render={(props) => (
    <StyledPopup {...props}>
      Content
    </StyledPopup>
  )}
/>
Base UI是完全无样式的，你可以选择以下方式：
1. Tailwind CSS（推荐）
tsx
<Dialog.Popup
  render={(props) => (
    <div {...props} className="bg-white rounded-lg shadow-xl p-6">
      内容
    </div>
  )}
/>
2. CSS Modules
tsx
import styles from "./Dialog.module.css";

<Dialog.Popup
  render={(props) => (
    <div {...props} className={styles.popup}>
      内容
    </div>
  )}
/>
3. Emotion/Styled Components
tsx
import styled from "@emotion/styled";

const StyledPopup = styled.div`
  background: white;
  border-radius: 8px;
  padding: 24px;
`;

<Dialog.Popup
  render={(props) => (
    <StyledPopup {...props}>
      内容
    </StyledPopup>
  )}
/>

Accessibility Best Practices

可访问性最佳实践

Base UI handles accessibility automatically:
✅ ARIA attributes - Applied via spread props ✅ Keyboard navigation - Tab, Escape, Arrow keys ✅ Focus management - Auto-focus, focus trapping ✅ Screen reader - Proper announcements
Always verify:
  • Spread 
    {...props}
    from render functions
  • Test with keyboard only
  • Test with screen reader (NVDA, JAWS, VoiceOver)
  • Check contrast ratios (WCAG AA minimum)
Base UI自动处理可访问性：
✅ ARIA属性 - 通过属性展开自动应用 ✅ 键盘导航 - Tab、Escape、方向键支持 ✅ 焦点管理 - 自动聚焦、焦点捕获 ✅ 屏幕阅读器支持 - 正确的内容播报
务必验证：
  • 从render函数中展开
    {...props}
  • 仅使用键盘进行测试
  • 使用屏幕阅读器测试（NVDA、JAWS、VoiceOver）
  • 检查对比度（符合WCAG AA最低标准）

Troubleshooting

故障排除

Problem: Render prop component not responding to clicks

问题：Render prop组件不响应点击

Solution: Ensure you're spreading 
{...props}
:
tsx
// ❌ Wrong
<Trigger render={() => <button>Click</button>} />

// ✅ Correct
<Trigger render={(props) => <button {...props}>Click</button>} />
解决方法：确保你展开了
{...props}
：
tsx
// ❌ 错误写法
<Trigger render={() => <button>点击</button>} />

// ✅ 正确写法
<Trigger render={(props) => <button {...props}>点击</button>} />

Problem: Popup appearing at wrong position

问题：弹窗显示位置错误

Solution: Wrap in Positioner:
tsx
// ❌ Wrong
<Popover.Popup />

// ✅ Correct
<Popover.Positioner side="top">
  <Popover.Portal>
    <Popover.Popup />
  </Popover.Portal>
</Popover.Positioner>
解决方法：用Positioner包裹：
tsx
// ❌ 错误写法
<Popover.Popup />

// ✅ 正确写法
<Popover.Positioner side="top">
  <Popover.Portal>
    <Popover.Popup />
  </Popover.Portal>
</Popover.Positioner>

Problem: TypeScript error "Property 'align' does not exist"

问题：TypeScript报错“Property 'align' does not exist”

Solution: Use 
alignment
not 
align
:
tsx
// ❌ Wrong (Radix)
<Positioner align="center" />

// ✅ Correct (Base UI)
<Positioner alignment="center" />
解决方法：使用
alignment
而非
align
：
tsx
// ❌ 错误写法（Radix）
<Positioner align="center" />

// ✅ 正确写法（Base UI）
<Positioner alignment="center" />

Problem: Arrow is invisible

问题：Arrow组件不可见

Solution: Style the arrow explicitly:
tsx
// ❌ Wrong
<Arrow />

// ✅ Correct
<Arrow render={(props) => (
  <div {...props} className="w-3 h-3 rotate-45 bg-white border" />
)} />
解决方法：显式设置Arrow样式：
tsx
// ❌ 错误写法
<Arrow />

// ✅ 正确写法
<Arrow render={(props) => (
  <div {...props} className="w-3 h-3 rotate-45 bg-white border" />
)} />

Problem: Tooltip not showing on disabled button

问题：禁用按钮的Tooltip不显示

Solution: Wrap button in span:
tsx
// ❌ Wrong
<Tooltip.Trigger render={(props) => <button {...props} disabled />} />

// ✅ Correct
<Tooltip.Trigger render={(props) => (
  <span {...props}><button disabled /></span>
)} />
解决方法：用span包裹按钮：
tsx
// ❌ 错误写法
<Tooltip.Trigger render={(props) => <button {...props} disabled />} />

// ✅ 正确写法
<Tooltip.Trigger render={(props) => (
  <span {...props}><button disabled /></span>
)} />
