## 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} />;
|
|
```
