## FAQ
### How to hide file icon when use showLine?
File icon realize by using switcherIcon. You can overwrite the style to hide it: <https://codesandbox.io/s/883vo47xp8>
### Why defaultExpandAll not working on ajax data?
`default` prefix prop only works when initializing. So `defaultExpandAll` has already executed when ajax load data. You can control `expandedKeys` or render Tree when data loaded to realize expanded all.

## FAQ
### 在 showLine 时，如何隐藏子节点图标？
文件图标通过 switcherIcon 来实现，如果不需要你可以覆盖对应的样式：<https://codesandbox.io/s/883vo47xp8>
### defaultExpandAll 在异步加载数据时为何不生效？
`default` 前缀属性只有在初始化时生效，因而异步加载数据时 `defaultExpandAll` 已经执行完成。你可以通过受控 `expandedKeys` 或者在数据加载完成后渲染 Tree 来实现全部展开。
