#### CountConfig

```tsx
interface CountConfig {
  // Max character count. Different from the native `maxLength`, it will be marked warning but not truncated
  max?: number;
  // Custom character count, for example, the standard emoji length is greater than 1, you can customize the counting strategy to change it to 1
  strategy?: (value: string) => number;
  // Same as `showCount`
  show?: boolean | ((args: { value: string; count: number; maxLength?: number }) => ReactNode);
  // Custom clipping logic when the number of characters exceeds `count.max`, no clipping when not configured
  exceedFormatter?: (value: string, config: { max: number }) => string;

## FAQ

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

When Input dynamic add or remove `prefix/suffix/showCount` 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} />;
```

### Why TextArea in control can make `value` exceed `maxLength`?

When in control, component should show as what it set to avoid submit value not align with store value in Form.
