## 动态选项
|
|
|
|
|
|
|
|
|
|
通过 source 可以从上下文或 api 中获取选项信息，比如
|
|
|
|
|
|
|
|
|
|
```schema: scope="body"
|
|
|
|

|
|
|
|

"options": [
|
|
|
|

|
|
|
|
|
"label": "A",
|
|
|
|
|
"value": "a"
|
|
|
|
|
},
|
|
|
|
|
{
|
|
|
|

|
|
|

|
|
|
|
|
},
|
|
|
|
|
{
|
|

"label": "B-2",
|
|
|
|

"value": "b-2"
|
|
|

},
|
|

## 只允许选中叶子节点
|
|
|
|
|
|
|
|
|
|
> 1.8.0 及以上版本，如果是之前版本可以在对应的节点上不设置 value 实现
|
|
|
|
|
|
|
|
|
|
在单选时，可以通过 `onlyLeaf` 来设置只允许选择叶子节点，即便分支节点有 `value` 也不会被选中。

|
|
|
在多选时，也可以通过 `onlyLeaf` 并且搭配 `cascade` 来设置只允许选择叶子节点，即便分支节点有 `value` 也不会有选中动作,

## 选中父节点，值是否包含子节点

默认选中父节点，是不会带上子节点的值，想要自动带上子节点的值，那么配置`"withChildren": true`

## 仅展示选中节点文本信息

## 选项搜索
|
|
|
|
|
|
|
|
|
|
配置`"searchable": true`后，输入框内输入内容时，下拉数据源会进行前端过滤，过滤的关键字段默认为`value`或`label`。如果通过[`valueField`](./options#选项值字段-valuefield)或[`labelField`](./options#选项标签字段-labelfield)属性，则会选择对应的字段进行过滤。

## 限制标签最大展示数量
|

|
|
|
|
|
> 3.3.0 及以上版本
|
|
|
|
|

|
`maxTagCount`可以限制标签的最大展示数量，超出数量的部分会收纳到 Popover 中，可以通过`overflowTagPopover`配置 Popover 相关的[属性](../tooltip#属性表)，注意该属性仅在多选模式开启后生效。
