该组件的功能有:

1.可设置搜索功能

2.可以每级可选,也可以选择只能最后一级里面的选项可选

3.当组件是只能最后一级里面的选项可选时, 点击文字展开下级选项

treeData数据示例:
  const arr0 = [
    {
      id: 1,
      pId: 0,
      value: 'leaf-1',
      title: '属性图1'
    },
    {
      id: 2,
      pId: 1,
      value: 'leaf-2',
      title: '属性图2'
    },
    {
      id: 3,
      pId: 0,
      value: 'leaf-3',
      title: '属性图3'
    }
  ];
  let [treeData, setTreeData] = useState(arr0);

CustomSimpleTreeSelect的简单使用:
            option={treeData}
          labelStyle={labelStyle}
          containerStyle={containerStyle}
          addAll={false}
          name="xxx"
          label="xxx"
          required
        />
