mui select上的示例代码::
这是我更改为他们的代码的方法:
import * as React from 'react';
import { useTheme } from '@mui/material/styles';
import Box from '@mui/material/Box';
import OutlinedInput from '@mui/material/OutlinedInput';
import InputLabel from '@mui/material/InputLabel';
import MenuItem from '@mui/material/MenuItem';
import FormControl from '@mui/material/FormControl';
import Select from '@mui/material/Select';
import Chip from '@mui/material/Chip';
const ITEM_HEIGHT = 48;
const ITEM_PADDING_TOP = 8;
const MenuProps = {
PaperProps: {
style: {
maxHeight: ITEM_HEIGHT * 4.5 + ITEM_PADDING_TOP,
width: 250,
},
},
};
const names = [
'Oliver Hansen',
'Van Henry',
'April Tucker',
'Ralph Hubbard',
'Omar Alexander',
'Carlos Abbott',
'Miriam Wagner',
'Bradley Wilkerson',
'Virginia Andrews',
'Kelly Snyder',
];
function getStyles(name, personName, theme) {
return {
fontWeight: personName.includes(name)
? theme.typography.fontWeightMedium
: theme.typography.fontWeightRegular,
};
}
export default function MultipleSelectChip() {
const theme = useTheme();
const [personName, setPersonName] = React.useState([]);
const handleChange = (event) => {
const {
target: { value },
} = event;
setPersonName(
// On autofill we get a stringified value.
typeof value === 'string' ? value.split(',') : value,
);
};
const handleDelete = (nameToDelete) => {
setPersonName((names) =>
names.filter((name) => name !== nameToDelete)
);
};
return (
<div>
<FormControl sx={{ m: 1, width: 300 }}>
<InputLabel id="demo-multiple-chip-label">Chip</InputLabel>
<Select
labelId="demo-multiple-chip-label"
id="demo-multiple-chip"
multiple
value={personName}
onChange={handleChange}
input={<OutlinedInput id="select-multiple-chip" label="Chip" />}
renderValue={(selected) => (
<Box sx={{ display: 'flex', flexWrap: 'wrap', gap: 0.5 }}>
{selected.map((value) => (
<Chip
key={value}
label={value}
onDelete={(event) => {
event.stopPropagation(); // Prevent the select dropdown from opening
handleDelete(value);
}}
/>
))}
</Box>
)}
MenuProps={MenuProps}
>
{names.map((name) => (
<MenuItem
key={name}
value={name}
style={getStyles(name, personName, theme)}
>
{name}
</MenuItem>
))}
</Select>
</FormControl>
</div>
);
}
是在我向Codium核对的情况下,它建议添加此部分:
event.stopPropagation();
有人有任何想法吗?
这是SandBox提供更高的元素将起作用。
<Chip
sx={{ zIndex: 9999 }}
key={value}
label={value}
onDelete={(event) => {
console.log("Deleting...");
event.stopPropagation();
handleDelete(value);
}}
/>
检查此工作demo.说,对于MultiSelect UI,我认为您可以使用材料AutoCocteTe组件,因为它具有内置功能来处理删除所选项目。
