When using TextField component as a Select field with a large data set (1000 items), there is noticeable delay when mounting / unmounting the list.
import React from 'react';
import MenuItem from '@material-ui/core/MenuItem';
import TextField from '@material-ui/core/TextField';
const TextFieldSelect = () => {
const [value, setValue] = React.useState('');
return (
<TextField
select
onChange={newValue => setValue(newValue)}
value={value}
>
{listWith1000Items.map(item => (
<MenuItem key={index} value={index}>
`Item ${index + 1}`
</MenuItem>
)}
</TextField>
)
};
As suggested in the docs, I'm using react-window to efficiently render the large list, but as a result - I lose the functionality of being able to select the list items.
import React from 'react';
import MenuItem from '@material-ui/core/MenuItem';
import TextField from '@material-ui/core/TextField';
import { FixedSizeList } from 'react-window';
const Row = ({ index, style }) => (
<MenuItem key={index} value={index} style={style}>
`Item ${index + 1}`
</MenuItem>
)
const WindowTextFieldSelect = () => {
const [value, setValue] = React.useState('');
return (
<TextField
select
onChange={newValue => setValue(newValue)}
value={value}
>
<FixedSizedList
height={960}
width={480}
itemSize={48}
itemCount={1000}
>
{Row}
</FixedSizedList>
</TextField>
)
};
I expect that when I select an item, the value gets updated.
