zh-CN: 响应式 maxTagCount
|
|
en-US: Responsive maxTagCount
|
|

## zh-CN
|
|
|
|
多选下通过响应式布局让选项自动收缩。该功能对性能有所消耗，不推荐在大表单场景下使用。
|
|
|
|
## en-US
|
|
|
|
Auto collapse to tag with responsive case. Not recommend use in large form case since responsive calculation has a perf cost.

```tsx
|
|
import { Select, Space } from 'antd';
|
|
|
|
interface ItemProps {
|
|
label: string;
|
|
value: string;
|
|
}
|
|
|
|
const options: ItemProps[] = [];
|
|
|
|
for (let i = 10; i < 36; i++) {
|
|
const value = i.toString(36) + i;
|
|
options.push({
|
|
label: `Long Label: ${value}`,
|
|
value,
|
|
});
|
|
}
|
|
|
|
const Demo = () => {
|
|
const [value, setValue] = React.useState(['a10', 'c12', 'h17', 'j19', 'k20']);
