## 父子之间不受控

设置treeCheckStrictly为true可以让父子之间不受控，但是labelInValue强制为true

```json
{
    "body": [{
        "type": "container",
        "model": "treeStrictly",
        "children": [{
            "type": "treeSelect",
            "name": "tree",
            "allowClear": true,
            "treeCheckable": true,
            "treeCheckStrictly": true,
            "options": [
                {
                   "title": "AAA",
                   "key": "aaa"
                },
                {
                   "title": "BBB",
                   "key": "bbb"
                },
                {
                   "title": "CCC",
                   "key": "ccc",
                   "children": [
                       {
                           "title": "DDD",
                           "key": "ddd"
                       },
                       {
                           "title": "EEE",
                           "key": "eee",
                           "children": []
                       }
                   ]
                }
            ]
        }, {
            "type": "text",
            "text": "#ES{$data.tree}"
        }]
    }]
}
```
