## FAQ

### Why Input lose focus when change `prefix/suffix`

When Input dynamic add or remove `prefix/suffix` will make React recreate the dom structure and new input will be not focused. You can set an empty `<span />` element to keep the dom structure:

```jsx
const suffix = condition ? <Icon type="smile" /> : <span />;

<Input suffix={suffix} />;
```
