在[穿梭器Transfer](./transfer)的基础上扩充了弹窗选择模式,展示值用的是简单的 input 框,但是编辑的操作是弹窗个穿梭框来完成。
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"body": [
{
"label": "组合穿梭器",
"type": "transfer-picker",
"name": "a",
"sortable": true,
"selectMode": "tree",
"searchable": true,
"options": [
{
"label": "法师",
"children": [
{
"label": "诸葛亮",
"value": "zhugeliang"
}
]
},
{
"label": "战士",
"children": [
{
"label": "曹操",
"value": "caocao"
},
{
"label": "钟无艳",
"value": "zhongwuyan"
}
]
},
{
"label": "打野",
"children": [
{

```
## 自定义选项展示
```schema: scope="body"
{
"type": "form",
"body": [
{
"label": "默认",
"type": "transfer-picker",
"name": "transfer",
"menuTpl": "<div class='flex justify-between'><span>${label}</span><span class='text-muted m-r text-sm'>${tag}</span></div>",
"valueTpl": "${label}(${value})",
"options": [
{
"label": "诸葛亮",
"value": "zhugeliang",
"tag": "法师",
},
{
"label": "曹操",
"value": "caocao",
"tag": "战士",

}
```
## 属性表
更多配置请参考[穿梭器Transfer](./transfer)。
## 事件表
当前组件会对外派发以下事件,可以通过`onEvent`来监听这些事件,并通过`actions`来配置执行的动作,在`actions`中可以通过`event.data.xxx`事件参数变量来获取事件产生的数据,详细请查看[事件动作](../../docs/concepts/event-action)。
| 事件名称 | 事件参数 | 说明 |
| -------- | --------------------------------- | -------------------------------- |
| change | `event.data.value: string` 选中值 | picker 弹窗确认提交时触发 |
| focus | - | 输入框获取焦点(非内嵌模式)时触发 |
| blur | - | 输入框失去焦点(非内嵌模式)时触发 |
## 动作表
当前组件对外暴露以下特性动作,其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作,动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数,详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。
| 动作名称 | 动作配置 | 说明 |
| -------- | ------------------------ | ------------------------------------------------------ |
| clear | - | 清空 |
| reset | - | 将值重置为`resetValue`,若没有配置`resetValue`,则清空 |
| setValue | `value: string` 更新的值 | 更新数据,多值用`,`分隔 |
