## 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} / > ;
```
