代码演示
如何引入
import { OverflowList } from '@douyinfe/semi-ui';
折叠模式 - 默认
通过 renderMode="collapse" (默认) 来实现内容的折叠。
import React from 'react';
import { OverflowList, Tag, Slider } from '@douyinfe/semi-ui';
import { IconAlarm, IconBookmark, IconCamera, IconDuration, IconEdit, IconFolder } from '@douyinfe/semi-icons';
() => {
const [width, setWidth] = useState(100);
const renderOverflow = items => {
return items.length ? <Tag style={{ flex: '0 0 auto' }}>+{items.length}</Tag> : null;
};
const renderItem = (item, ind) => {
return (
<Tag color="blue" key={item.key} style={{ marginRight: 8, flex: '0 0 auto' }}>
{item.icon}
{item.key}
</Tag>
);
};
const items = [
{ icon: <IconAlarm style={{ marginRight: 4 }} />, key: 'alarm' },
{ icon: <IconBookmark style={{ marginRight: 4 }} />, key: 'bookmark' },
{ icon: <IconCamera style={{ marginRight: 4 }} />, key: 'camera' },
{ icon: <IconDuration style={{ marginRight: 4 }} />, key: 'duration' },
{ icon: <IconEdit style={{ marginRight: 4 }} />, key: 'edit' },
{ icon: <IconFolder style={{ marginRight: 4 }} />, key: 'folder' },
];
return (
<div>
<Slider step={1} value={width} onChange={value => setWidth(value)} />
<br />
<br />
<div style={{ width: `${width}%` }}>
<OverflowList items={items} overflowRenderer={renderOverflow} visibleItemRenderer={renderItem} />
</div>
</div>
);
};
折叠模式 - 方向
collapse 模式下支持 collapseFrom 设置折叠方向。
import React from 'react';
import { OverflowList, Tag, Slider } from '@douyinfe/semi-ui';
import { IconAlarm, IconBookmark, IconCamera, IconDuration, IconEdit, IconFolder } from '@douyinfe/semi-icons';
() => {
const [width, setWidth] = useState(100);
const renderOverflow = items => {
return items.length ? <Tag style={{ marginRight: 8, flex: '0 0 auto' }}>+{items.length}</Tag> : null;
};
const renderItem = (item, ind) => {
return (
<Tag color="blue" key={item.key} style={{ marginRight: 8, flex: '0 0 auto' }}>
{item.icon}
{item.key}
</Tag>
);
};
const items = [
{ icon: <IconAlarm style={{ marginRight: 4 }} />, key: 'alarm' },
{ icon: <IconBookmark style={{ marginRight: 4 }} />, key: 'bookmark' },
{ icon: <IconCamera style={{ marginRight: 4 }} />, key: 'camera' },
{ icon: <IconDuration style={{ marginRight: 4 }} />, key: 'duration' },
{ icon: <IconEdit style={{ marginRight: 4 }} />, key: 'edit' },
{ icon: <IconFolder style={{ marginRight: 4 }} />, key: 'folder' },
];
return (
<div>
<Slider step={1} value={width} onChange={value => setWidth(value)} />
<br />
<br />
<div style={{ width: `${width}%` }}>
<OverflowList
items={items}
collapseFrom="start"
overflowRenderer={renderOverflow}
visibleItemRenderer={renderItem}
/>
</div>
</div>
);
};
折叠模式 - 最小展示的数目
collapse 模式下支持 minVisibleItems 设置最小展示的数目。
import React from 'react';
import { OverflowList, Tag, Slider } from '@douyinfe/semi-ui';
import { IconAlarm, IconBookmark, IconCamera, IconDuration, IconEdit, IconFolder } from '@douyinfe/semi-icons';
() => {
const [width, setWidth] = useState(100);
const renderOverflow = items => {
return items.length ? <Tag style={{ flex: '0 0 auto' }}>+{items.length}</Tag> : null;
};
const renderItem = (item, ind) => {
return (
<Tag color="blue" key={item.key} style={{ marginRight: 8, flex: '0 0 auto' }}>
{item.icon}
{item.key}
</Tag>
);
};
const items = [
{ icon: <IconAlarm style={{ marginRight: 4 }} />, key: 'alarm' },
{ icon: <IconBookmark style={{ marginRight: 4 }} />, key: 'bookmark' },
{ icon: <IconCamera style={{ marginRight: 4 }} />, key: 'camera' },
{ icon: <IconDuration style={{ marginRight: 4 }} />, key: 'duration' },
{ icon: <IconEdit style={{ marginRight: 4 }} />, key: 'edit' },
{ icon: <IconFolder style={{ marginRight: 4 }} />, key: 'folder' },
];
return (
<div>
<Slider step={1} value={width} onChange={value => setWidth(value)} />
<br />
<br />
<div style={{ width: `${width}%` }}>
<OverflowList
items={items}
minVisibleItems={3}
overflowRenderer={renderOverflow}
visibleItemRenderer={renderItem}
/>
</div>
</div>
);
};
滚动模式
通过 renderMode="scroll" 来使用滚动模式的折叠列表。如果需要 scrollIntoView，可以通过选择器： document.querySelector(`.item-cls[data-scrollkey="${key}"] 来选取。
import React from 'react';
import { OverflowList, Tag, Slider } from '@douyinfe/semi-ui';
import { IconAlarm, IconBookmark, IconCamera, IconDuration, IconEdit, IconFolder } from '@douyinfe/semi-icons';
() => {
const [width, setWidth] = useState(100);
const renderOverflow = items => {
return items.map(item => <Tag style={{ marginRight: 8, marginLeft: 8, flex: '0 0 auto' }} key={item.key}>+{item.length}</Tag>);
};
const renderItem = (item, ind) => {
return (
<span key={item.key} className="item-cls">
<Tag color="blue" style={{ marginRight: 8, flex: '0 0 auto' }}>
{item.icon}
{item.key}
</Tag>
</span>
);
};
const items = [
{ icon: <IconAlarm style={{ marginRight: 4 }} />, key: 'alarm' },
{ icon: <IconBookmark style={{ marginRight: 4 }} />, key: 'bookmark' },
{ icon: <IconCamera style={{ marginRight: 4 }} />, key: 'camera' },
{ icon: <IconDuration style={{ marginRight: 4 }} />, key: 'duration' },
{ icon: <IconEdit style={{ marginRight: 4 }} />, key: 'edit' },
{ icon: <IconFolder style={{ marginRight: 4 }} />, key: 'folder' },
];
return (
<div>
<Slider step={1} value={width} onChange={value => setWidth(value)} />
<br />
<br />
<div style={{ width: `${width}%` }}>
<OverflowList
items={items}
renderMode="scroll"
overflowRenderer={renderOverflow}
visibleItemRenderer={renderItem}
/>
</div>
</div>
);
};
