How to handle arrays in a Grommet DataTable?

I'm trying to use arrays in Grommet DataTable. My data looks like this :
{
customer: [
'BANANA',
'Banana',
'banana',
'republic of banana'
],
somethingelse: ['ABC','123','DEF']
}
In a regular Grommet Table , I'm able to use every cell by defining the first value from the array as title - for example customer[0] - and create an expandable arrow to show the rest of the data in 'customer' :
But I don't get how to do this on a cell basis for a Grommet DataTable ?
Here is the way I'm using it in the regular Grommet Table :
<TableCell scope="row" pad={{ left: '2px', righ: '3px' }}>
<TextInput name="tags" size="xsmall" />
</TableCell>
</TableRow>
{searchResults.length > 0 &&
searchResults.map((searchResult, index) => (
<TableRow key={index}>
<TableCell>
<Box direction="row">
<Text size="xsmall">{searchResult.customer[0]}</Text>
{searchResult.customer.length > 1 && (
<Button
plain
hoverIndicator={false}
icon={
isExpanded[index] ? (
<FormDown size="18px" />
) : (
<FormNext size="18px" />
)
}
onClick={() => toggleOpen(index)}
/>
)}
</Box>
<Box>
{isExpanded[index] && listElements(searchResult.customer)}
</Box>
</TableCell>
Here is my Form , using DataTable :
return (
<Form value={formData} onSubmit={onSubmit} onChange={onChange}>
...
<DataTable
fill
border={{ body: 'bottom' }}
paginate
columns={columns}
data={searchResults}
select={select}
onClickRow={(e) => console.log(e.datum)}
onSelect={() => {}}
step={8}
rowDetails={(row) => { // I'm able to use rowDetails to expand and display some data , but how can I use this to 1. Use the [0] element of the array as title and 2. apply to all cells in the row/table.
for (const cell in row) {
// if (cell.length > 1) {
// return listElements(cell);
// }
console.log(cell);
}
}}
...
/>
...
</Form>
);

I was able to achieve that by using the render function and passing a CellElement to it, in which I have created my rules :
const columns = [
{
property: 'customer',
header: <FormField label="Customer" name="customer" size="xsmall" />,
render: (datum) => <CellElement val={datum.customer} />,
},
CellElement.js
import { Box, Text, Button } from 'grommet';
import { FormNext, FormDown } from 'grommet-icons';
import React, { useState } from 'react';
const CellElement = ({ val }) => {
const title = Array.isArray(val) ? val[0] : val;
const [isExpanded, setIsExpanded] = useState({});
const toggleOpen = (category) => {
setIsExpanded({
...isExpanded,
[category]: !isExpanded[category],
});
};
const listElements = (arr) => {
return arr.slice(1).map((el, index) => (
<Text key={index} size="xsmall">
{el}
</Text>
));
};
return (
<Box>
<Box direction="row">
<Text size="xsmall">{title}</Text>
{Array.isArray(val) && val.length > 1 && (
<Button
plain
hoverIndicator={false}
icon={
isExpanded[title] ? (
<FormDown size="18px" />
) : (
<FormNext size="18px" />
)
}
onClick={() => toggleOpen(title)}
/>
)}
</Box>
<Box>{isExpanded[title] && listElements(val)}</Box>
</Box>
);
};
export default CellElement;

React typescript onChange is showing error when I try to add it to material UI switch

I am planning to do a show and hide using switch. When I turn on the switch it need to show the component and when I turn odd the switch it need to hide the component.
This is the coding I did.
export const VirtualEventSection = ({
control,
onSearch,
onSearchInputChange,
searchInputValue,
}: VirtualEventSectionProps) => {
const { formatMessage } = useLocale();
const styles = useStyles();
const [state, setState] = useState(false);
const handleSwitchChange = (event: React.ChangeEvent<HTMLInputElement>) => {
setState(event.target.checked);
};
return (
<Card className={styles.actionCard}>
<Grid container spacing={1} alignItems="flex-start">
<Grid item sm={12} xs={12}>
<SwitchWithLabel
name="virtualEnabled"
label={formatMessage({ id: 'form_event.event_toggle_lable' })}
control={control}
checked={state}
onChange={handleSwitchChange}
/>
{state && state === true ? (
<LocationSelection
control={control}
onSearch={onSearch}
onSearchInputChange={onSearchInputChange}
searchInputValue={searchInputValue}
/>
) : (
<h1></h1>
)}
</Grid>
</Grid>
</Card>
);
};
But when I add like this I am getting an error in onChange. This is the error I got
Type '(event: React.ChangeEvent<HTMLInputElement>) => void' is not assignable to type '({ name, checked }: OnChangeProps<"virtualEnabled">) => void'. Types of parameters 'event' and '__0' are incompatible.Type 'OnChangeProps<"virtualEnabled">' is missing the following properties from type 'ChangeEvent<HTMLInputElement>': target, nativeEvent, currentTarget, bubbles, and 11 more.
This is the created switchWithLable component
export const SwitchWithLabel = <T extends string = string>({
label,
name,
control,
...switchProps
}: SwitchWithLabelProps<T>) => {
const styles = useStyles();
return (
<Controller
name={name}
control={control}
render={({ value, onChange }) => (
<FormControlLabel
className={styles.label}
label={label}
control={
<Switch
name={name}
onChange={async ({ checked }) => {
onChange(checked);
}}
checked={value}
{...switchProps}
/>
}
/>
)}
/>
);
};
Can any one help me to achieve the goal. I tried multiple time and still showing the error.

You don't need to have event: React.ChangeEvent<HTMLInputElement>. You can change the state of the switch with simple function.
const handleSwitchChange = () => {
setState(!state);
};
Complete code =>
export const VirtualEventSection = ({
control,
onSearch,
onSearchInputChange,
searchInputValue,
}: VirtualEventSectionProps) => {
const { formatMessage } = useLocale();
const styles = useStyles();
const [state, setState] = useState(false);
const handleSwitchChange = () => {
setState(!state);
};
return (
<Card className={styles.actionCard}>
<Grid container spacing={1} alignItems="flex-start">
<Grid item sm={12} xs={12}>
<SwitchWithLabel
name="virtualEnabled"
label={formatMessage({ id: 'form_event.event_toggle_lable' })}
control={control}
checked={state}
onChange={() => handleSwitchChange()}
/>
{state && state === true ? (
<LocationSelection
control={control}
onSearch={onSearch}
onSearchInputChange={onSearchInputChange}
searchInputValue={searchInputValue}
/>
) : (
<h1></h1>
)}
</Grid>
</Grid>
</Card>
);
};

Multiple Select with options as an object array

I have the following component for selecting roles:
export const MultipleSelectChip = ({
options,
label,
error,
onRolesUpdate,
}: Props) => {
const theme = useTheme();
const [selectedOptions, setSelectedOptions] = React.useState<string[]>([]);
const handleChipChange = (
event: SelectChangeEvent<typeof selectedOptions>,
) => {
const {
target: { value },
} = event;
setSelectedOptions(
// On autofill we get a the stringified value.
typeof value === 'string' ? value.split(',') : value,
);
};
return (
<div>
<FormControl sx={{ m: 1, width: 300 }}>
<InputLabel id="multiple-chip-label">{label}</InputLabel>
<Select
required
labelId="multiple-chip-label"
error={error}
id="demo-multiple-chip"
multiple
value={selectedOptions}
onChange={handleChipChange}
input={<OutlinedInput id="select-multiple-chip" label={label} />}
renderValue={(selected) => (
<Box sx={{ display: 'flex', flexWrap: 'wrap', gap: 0.5 }}>
{selected.map((value) => (
<Chip key={value} label={value} />
))}
</Box>
)}
MenuProps={MenuProps}
>
{options.map((propOption) => (
<MenuItem
key={propOption.id}
value={propOption.name}
style={getStyles(propOption, selectedOptions, theme)}
>
{propOption.name}
</MenuItem>
))}
</Select>
<FormHelperText>Here's my helper text</FormHelperText>
</FormControl>
</div>
);
};
For options I have an array of objects with id and name, the thing is that I want to use the names for displaying the chips and the ids to pass them to the parent component for the add request. I don't know how to get de ids, too.
This is the example: https://codesandbox.io/s/6ry5y?file=/demo.tsx but is using an array of strings instead of an array of objects.
This is how 'options' looks like:
const rolesDummy: Role[] = [
{ id: '61fb0f25-34aa-46c6-8683-093254223dcd', name: 'HR' },
{ id: '949b9b1e-d3f8-45cb-a061-08da483bd486', name: 'Interviewer' },
{ id: 'c09ae2d4-1335-4ef0-8d4b-ee9529796b52', name: 'Hiring Manager' },
];
And I need to get back only the selected ids
Thank you!

If you pass the option as an object, you can render each MenuItem with the option.id as a key and the option.name as the label. The MenuItem is identified by an id:
<Select {...}>
{options.map((option) => (
<MenuItem key={option.id} value={option.id}>
{option.name}
</MenuItem>
))}
</Select>
To display the name in the selected Chip. Use renderValue, but it only provides you the selected values (array of option.id), so you need to find the option to get the name:
renderValue={(selected) => {
return (
<Box>
{selected.map((value) => {
const option = options.find((o) => o.id === value);
return <Chip key={value} label={option.name} />;
})}
</Box>
);
}}
Now you can get an array of selected ids by adding a change handler:
onChange={e => console.log(e.target.value)}

Cant bind form to nested array properly in react js

I'm trying to bind to a nested array to text inputs from a form. There are 6 blocks and each block contains 3 values. I have initially populated the array for mapping by using:
new Array(6).fill(['','',''])
and rendering the values using 2 loops. One for the 6 blocks and the other 3 values inside each block. The 3 values are the ones binding to the form. I refer to each of the inputs using the second parameter of the map function which is the index.
Here is the code in its entirety.
import {
Card,
CardContent,
CardHeader,
CardMedia,
TextField,
Grid,
Typography,

} from "#material-ui/core";
import axios from "axios";
import { useState } from "react";
import { useHistory } from "react-router";
export default function CreateEditQuestion() {
const answerPack = new Array(6).fill(["", "", ""]);
const [question, setQuestion] = useState("");
const [answers, setAnswer] = useState(answerPack);
const [TimeAllowed, setTimeAllowed] = useState(30);
const [Score, setScore] = useState(1);
const [Date, setDate] = useState("");
const history = useHistory();
const handleAnswerSet = (value, answerIndex, answerTextIndex) => {
var updatedAnswer = answers;
updatedAnswer[answerIndex][answerTextIndex] = value;
setAnswer(updatedAnswer);
};
const handleSubmit = () => {
let data = {
question,
answer_set: answers,
time_allowed: TimeAllowed,
score_value: Score,

};
for (const [key, value] of Object.entries({ question, Date })) {
if (value.trim().length == 0) {
alert(`${key} has not been filled in`);
return false;
}
}
axios
.post(
"https://localhost:8000/question",
data
)
.then((resp) => {
alert("Succesfully added Question");
history.push("/question");
})
.catch((err) => {
console.log(err);
});
};
return (

Problem:
On each block, changing any value also changes all the other corresponding inputs in other blocks, so if the first input on the first block is changed, then all other first inputs in the other blocks also get changed,e.g(changing answer 1-1 also changes 2-1,3-1,4-1, etc). I could not trace why. Only the corresponding values should be changed
This is the function responsible for setting the values.
const handleAnswerSet = (value, answerIndex, answerTextIndex) => {
var updatedAnswer = answers;
updatedAnswer[answerIndex][answerTextIndex] = value;
setAnswer(updatedAnswer);
};

React Hook useState value being reset to initial value

The state of a value set using React useState hook gets set to the proper value and then reset to null. Critical code below. The click event that sets the startDate to the current date and time is 3 components down from where startDate is initialized. When setStartDate did not work I created an arrow function, updateStartDate. Both had the same problem where the startDate was changed after the click event (witnessed per the console.log in the top component), but was null just before the next click event (per the console.log in the click event). This is not an async problem as I see the change made before subsequent click.
If this is something that just does not work please explain. I could probably fix with useReducer but prefer to keep the useState if there is something I can do to correct this... If not correctable then I would like to at least understand why it does not work so that I can avoid this problem in the future.
export const DisplayTicTacToeContainer = (props) => {
const [startDate, setStartDate]= useState();
const updateStartDate = (newDate) => {
setStartDate(newDate);
}
useEffect (() => {
setStartDate(null);
}, []);
useEffect(() => {
console.log( "displayTicTacToeContainer useEffect for change of startDate = ", startDate)
}, [startDate]);
return (
<DisplayTicTacToeMatch arrayOfMatchingItems ={arrayOfMatchingItems}
startDate={startDate}
setStartDate={setStartDate}
updateStartDate={updateStartDate}
/>);
}
//-----------------------------------------------
export const DisplayTicTacToeMatch = (props) => {
const { startDate,
setStartDate,
updateStartDate,
} = props;
useEffect(() => {
// Performs some prep and working fine.
}, []);
return (
<TicTacToe
startDate={startDate}
setStartDate={setStartDate}
updateStartDate={updateStartDate}
/>
);
}
//-----------------------------------------------
const TicTacToeContainer = (props) => {
const { startDate,
setStartDate,
updateStartDate,
} = props;
const [board, setBoard] = useState(<Board
updateStartDate={updateStartDate}
startDate={startDate}
setStartDate={setStartDate}/>);
return (
<Board/>
)
}
export default TicTacToeContainer;
I renamed the component to BoardComponent and the state variable to boardLayout. I included the full return portion of the BoardComponent below.
As I am still experiencing the problem I would agree with you that, "DisplayTicTacToeContainer is being mounted twice". Any thoughts on how I can avoid this from happening?
Other than this inability to setStartDate, everything is working fine.
//-----------------------------------------------
const Board = (props) => {
const { updateStartDate,
startDate,
setStartDate,
} = props;

At least, code below doesn't make much sense.
Please don't set state value as a component.
Also, try to name state variable different from components, since it will confuse you at some ppint.
const [board, setBoard] = useState(<Board
updateStartDate={updateStartDate}
startDate={startDate}
setStartDate={setStartDate}/>);
return (
<Board/>
)
Another possibility is that the DisplayTicTacToeContainer is being mounted twice, but I can't confirm it with the code provided.
