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。
## API
### Tree props
| 参数 | 说明 | 类型 | 默认值 | 版本 |
| --- | --- | --- | --- | --- | --- |
| allowClear | 显示清除按钮 | boolean | false | |
| defaultValue | 指定默认选中的条目 | string/string\[] | - | |
| disabled | 是否禁用 | boolean | false | |
| dropdownClassName | 下拉菜单的 className 属性 | string | - | |
| 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 | |
| dropdownStyle | 下拉菜单的样式 | object | - | |
| 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。 | 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: VNode, halfChecked(treeCheckStrictly 时有效): string[] }` 的格式 | boolean | false | |
| loadData | 异步加载数据 | function(node) | - | |
| maxTagCount | 最多显示多少个 tag | number | - | |
| maxTagPlaceholder | 隐藏 tag 时显示的内容 | slot/function(omittedValues) | - | |
| multiple | 支持多选(当设置 treeCheckable 时自动变为 true | boolean | false | |
| placeholder | 选择框默认文字 | string\|slot | - | |
| searchPlaceholder | 搜索框默认文字 | string\|slot | - | |
| searchValue(v-model) | 搜索框的值,可以通过 `search` 事件获取用户输入 | 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 | |
| showCheckedStrategy | 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. | enum{TreeSelect.SHOW_ALL, TreeSelect.SHOW_PARENT, TreeSelect.SHOW_CHILD } | TreeSelect.SHOW_CHILD | |
| showSearch | 在下拉中显示搜索框(仅在单选模式下生效) | boolean | false | |
| size | 选择框大小,可选 `large` `small` | string | 'default' | |
| suffixIcon | 自定义的选择框后缀图标 | VNode \| slot | - | |
| 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, label, children, [disabled, disableCheckbox, selectable]}> | \[] | |
| replaceFields | 替换 treeNode 中 title,value,key,children 字段为 treeData 中对应的字段 | object | {children:'children', label:'title', key:'key', value: 'value' } | | 1.6.1 (3.0.0 废弃) |
| fieldNames | 替换 treeNode 中 title,value,key,children 字段为 treeData 中对应的字段 | object | {children:'children', label:'title', key:'key', value: 'value' } | | 3.0.0 |
