树型选择控件。
## 何时使用
类似 Select 的选择控件,可选择的数据结构是一个树形结构时,可以使用 TreeSelect例如公司层级、学科系统、分类目录等等。
## 代码演示
<code src="./demo/basic.tsx">基本</code>
<code src="./demo/multiple.tsx">多选</code>
<code src="./demo/treeData.tsx">从数据直接生成</code>
<code src="./demo/checkable.tsx">可勾选</code>
<code src="./demo/async.tsx">异步加载</code>
<code src="./demo/treeLine.tsx">线性样式</code>
<code src="./demo/placement.tsx">弹出位置</code>
<code src="./demo/status.tsx">自定义状态</code>
<code src="./demo/suffix.tsx" debug>后缀图标</code>
<code src="./demo/render-panel.tsx" debug>_InternalPanelDoNotUseOrYouWillBeFired</code>
## API
### Tree props
| 参数 | 说明 | 类型 | 默认值 | 版本 |
| --- | --- | --- | --- | --- |
| allowClear | 显示清除按钮 | boolean | false | |
| autoClearSearchValue | 当多选模式下值被选择,自动清空搜索框 | boolean | true | |
| bordered | 是否显示边框 | boolean | true | |
| defaultValue | 指定默认选中的条目 | string \| string\[] | - | |
| disabled | 是否禁用 | boolean | false | |
| popupClassName | 下拉菜单的 className 属性 | string | - | 4.23.0 |
| dropdownMatchSelectWidth | 下拉菜单和选择器同宽。默认将设置 `min-width`当值小于选择框宽度时会被忽略。false 时会关闭虚拟滚动 | boolean \| number | true | |
| dropdownRender | 自定义下拉框内容 | (originNode: ReactNode, props) => ReactNode | - | |
| dropdownStyle | 下拉菜单的样式 | object | - | |
| fieldNames | 自定义节点 label、value、children 的字段 | object | { label: `label`, value: `value`, children: `children` } | 4.17.0 |
| filterTreeNode | 是否根据输入项进行筛选,默认用 treeNodeFilterProp 的值作为要筛选的 TreeNode 的属性值 | boolean \| function(inputValue: string, treeNode: TreeNode) (函数需要返回 bool 值) | function | |
| getPopupContainer | 菜单渲染父节点。默认渲染到 body 上,如果你遇到菜单滚动定位问题,试试修改为滚动的区域,并相对其定位。[示例](https://codepen.io/afc163/pen/zEjNOy?editors=0010) | function(triggerNode) | () => document.body | |
| labelInValue | 是否把每个选项的 label 包装到 value 中,会把 value 类型从 `string` 变为 {value: string, label: ReactNode, halfChecked(treeCheckStrictly 时有效): string\[] } 的格式 | boolean | false | |
| listHeight | 设置弹窗滚动高度 | number | 256 | |
| loadData | 异步加载数据 | function(node) | - | |
| maxTagCount | 最多显示多少个 tag响应式模式会对性能产生损耗 | number \| `responsive` | - | responsive: 4.10 |
| maxTagPlaceholder | 隐藏 tag 时显示的内容 | ReactNode \| function(omittedValues) | - | |

| placeholder | 选择框默认文字 | string | - | |
| placement | 选择框弹出的位置 | `bottomLeft` `bottomRight` `topLeft` `topRight` | bottomLeft | |
| searchValue | 搜索框的值,可以通过 `onSearch` 获取用户输入 | string | - | |
| showArrow | 是否显示 `suffixIcon`,单选模式下默认 `true` | boolean | - | |
| showCheckedStrategy | 配置 `treeCheckable` 时,定义选中项回填的方式。`TreeSelect.SHOW_ALL`: 显示所有选中节点(包括父节点)。`TreeSelect.SHOW_PARENT`: 只显示父节点(当父节点下所有子节点都选中时)。 默认只显示子节点 | `TreeSelect.SHOW_ALL` \| `TreeSelect.SHOW_PARENT` \| `TreeSelect.SHOW_CHILD` | `TreeSelect.SHOW_CHILD` | |
| showSearch | 是否支持搜索框 | boolean | 单选false \| 多选true | |
| size | 选择框大小 | `large` \| `middle` \| `small` | - | |
| status | 设置校验状态 | 'error' \| 'warning' | - | 4.19.0 |
| suffixIcon | 自定义的选择框后缀图标, 多选模式下必须同时设置 `showArrow` 为 true | ReactNode | - | |
| switcherIcon | 自定义树节点的展开/折叠图标 | ReactNode \| ((props: AntTreeNodeProps) => ReactNode) | - | renderProps: 4.20.0 |
| tagRender | 自定义 tag 内容,多选时生效 | (props) => ReactNode | - | |
| treeCheckable | 显示 Checkbox | boolean | false | |
| treeCheckStrictly | `checkable` 状态下节点选择完全受控(父子节点选中状态不再关联),会使得 `labelInValue` 强制为 true | boolean | false | |
| treeData | treeNodes 数据,如果设置则不需要手动构造 TreeNode 节点value 在整个树范围内唯一) | array&lt;{value, title, children, \[disabled, disableCheckbox, selectable, checkable]}> | \[] | |

| treeDefaultExpandAll | 默认展开所有树节点 | boolean | false | |
| treeDefaultExpandedKeys | 默认展开的树节点 | string\[] | - | |
| treeExpandAction | 点击节点 title 时的展开逻辑可选false \| `click` \| `doubleClick` | string \| boolean | false | 4.21.0 |
| treeExpandedKeys | 设置展开的树节点 | string\[] | - | |
| treeIcon | 是否展示 TreeNode title 前的图标,没有默认样式,如设置为 true需要自行定义图标相关样式 | boolean | false | |

## FAQ
### onChange 时如何获得父节点信息?
从性能角度考虑,我们默认不透出父节点信息。你可以这样获得:<https://codesandbox.io/s/wk080nn81k>
### 自定义 Option 样式导致滚动异常怎么办?
请参考 Select 的 [FAQ](/components/select)。
