How to send/receive props to BasicLayout (#devexpress/dx-react-scheduler)

I'm from Angular and new to React. Im doing well but here is a problem I'm stuck at. As you can see I have BasicLayout and AppointmentForm, both are in one file. BasicLayout is being used inside AppointmentForm but not like an element i.e <BasicLayout/> so I'm not able to understand how to pass props or its even possible now. I want to trigger commitChanges(inside AppointmentForm) function when onSubmit(inside Basic Layout) function is triggered. How can I pass props between these components?
const BasicLayout = (props) => {
const formik = useFormik({
initialValues: {
title: '',
agenda: '',
description: '',
participants: [],
host: user?.id,
guest: '',
location: '',
},
validationSchema,
onSubmit: async (values) => {
values.startDate = props.appointmentData.startDate;
values.endDate = props.appointmentData.endDate;
values.guest = values.guest?._id;
createAppointment(values);
console.log(values);
},
});
return (
<Container>
<Typography sx={{ fontSize: 24, fontWeight: 'bold' }} color="text.primary" gutterBottom>
Create Appointment
</Typography>
<Box sx={{ flexGrow: 1 }}>
<FormikProvider value={formik}>
<Form autoComplete="off" onSubmit={handleSubmit}>
<Grid container spacing={2}>
<Grid item xs={6} md={6}>
<TextField
label="Title"
color="secondary"
id="title"
type="text"
key="title"
value={formik.values.title}
onChange={formik.handleChange}
{...getFieldProps('title')}
error={Boolean(touched.title && errors.title)}
helperText={touched.title && errors.title}
fullWidth
/>
</Grid>
<Grid item container xs={12} md={12} direction="row" justifyContent="center" alignItems="center">
<LoadingButton size="medium" type="submit" variant="contained" loading={isSubmitting}>
Create
</LoadingButton>
</Grid>
</Grid>
</Form>
</FormikProvider>
</Box>
<ToastContainer />
</Container>
);
};
const AppointmentsDashboard = (props) => {
const commitChanges = ({ added, changed, deleted }) => {
console.log(props);
console.log({ added, changed, deleted });
if (added) {
if (!isValidate) {
notify('Please fill all required fields', 'error');
return;
}
const startingAddedId = data.length > 0 ? data[data.length - 1].id + 1 : 0;
setData([...data, { id: startingAddedId, ...added }]);
}
if (changed) {
setData(
data.map((appointment) =>
changed[appointment.id] ? { ...appointment, ...changed[appointment.id] } : appointment
)
);
}
if (deleted !== undefined) {
setData(data.filter((appointment) => appointment.id !== deleted));
}
return data;
};
return (

Cant Edit dynamic Textfield form graphql data in reactjs

I'm trying to create a dynamic textfield that takes data from gql like this
const { data } = useQuery(DATA_LIST, {
variables: {
param: {
limit: 10,
offset: 0,
sortBy: 'order'
}
}
});
const [state, setState] = useState<any>([]);
useEffect(() => {
if (data) {
setState(data?.dataList?.data);
}}, [data]);
then create a textField like this :
<TextField
name="name"
required
fullWidth
// label="Status Name"
onChange={(event) => handleChange(event, index)}
value={item?.name}
sx={{ marginRight: 5 }}
/>
<TextField
name="category"
required
fullWidth
select
// label="Category"
onChange={(event) => handleChange(event, index)}
value={item?.category}
>
{Category.map((option, index) => (
<MenuItem key={index} value={option.value}>
{option.name}
</MenuItem>
))}
</TextField>
handleChange :
const handleChangeInput = (
event: React.ChangeEvent<HTMLInputElement | HTMLTextAreaElement>,
index: number
) => {
const values = [...state];
values[index][event.target.name] = event.target.value;
console.log(values[index], 'ini values');
setState(values);
};
and call the inputRow component like this (im using drag and drop for textField list) :
{state.map((item: any, index: any) => {
// console.log(statusName[index]);
return (
<Draggable key={item.id} draggableId={String(item.id)} index={index}>
{(provided, snapshot): JSX.Element => (
<div
key={index}
ref={provided.innerRef}
{...provided.draggableProps}
{...provided.dragHandleProps}
style={getItemStyle(snapshot.isDragging, provided.draggableProps.style)}
>
<Box marginRight={2}>
<TypographyComponent text={index + 1} type={'subBody'} />
</Box>
<InputRow index={index} item={item} handleChange={handleChangeInput} />
</div>
)}
</Draggable>
);
})}
but when i try to type the textfield, an error appears that Cannot assign to read only property
error message
This is weird because if I input dummy data, the textfield can be modified, but if I use data from the API the data cannot be modified.

React - Close MUI drawer from nested menu

I'm using this excellent example (Nested sidebar menu with material ui and Reactjs) to build a dynamic nested menu for my application. On top of that I'm trying to go one step further and put it into a Material UI appbar/temporary drawer. What I'd like to achieve is closing the drawer when the user clicks on one of the lowest level item (SingleLevel) however I'm having a tough time passing the toggleDrawer function down to the menu. When I handle the click at SingleLevel I consistently get a 'toggle is not a function' error.
I'm relatively new to this so I'm sure it's something easy and obvious. Many thanks for any answers/comments.
EDIT: Here's a sandbox link
https://codesandbox.io/s/temporarydrawer-material-demo-forked-v11ur
Code is as follows:
Appbar.js
export default function AppBar(props) {
const [drawerstate, setDrawerstate] = React.useState(false);
const toggleDrawer = (state, isopen) => (event) => {
if (event.type === 'keydown' && (event.key === 'Tab' || event.key === 'Shift')) {
return;
}
setDrawerstate({ ...state, left: isopen });
};
return (
<Box sx={{ flexGrow: 1 }}>
<AppBar position="static" color="secondary">
<Toolbar>
<IconButton
size="large"
edge="start"
color="primary"
aria-label="menu"
onClick={toggleDrawer('left', true)}
>
<MenuIcon />
</IconButton>
<img src={logo} alt="logo" />
</Toolbar>
<Drawer
anchor='left'
open={drawerstate['left']}
onClose={toggleDrawer('left', false)}
>
<Box>
<AppMenu toggleDrawer={toggleDrawer} />
</Box>
</Drawer>
</AppBar>
</Box >
)
}
Menu.js
export default function AppMenu(props) {
return MenuItemsJSON.map((item, key) => <MenuItem key={key} item={item} toggleDrawer={props.toggleDrawer} />);
}
const MenuItem = ({ item, toggleDrawer }) => {
const MenuComponent = hasChildren(item) ? MultiLevel : SingleLevel;
return <MenuComponent item={item} toggleDrawer={toggleDrawer} />;
};
const SingleLevel = ({ item, toggleDrawer }) => {
const [toggle, setToggle] = React.useState(toggleDrawer);
return (
<ListItem button onClick={() => { toggle('left', false) }}>
<ListItemIcon>{item.icon}</ListItemIcon>
<ListItemText primary={item.title} />
</ListItem>
);
};
const MultiLevel = ({ item }) => {
const { items: children } = item;
const [open, setOpen] = useState(false);
const handleClick = () => {
setOpen((prev) => !prev);
};
return (
<React.Fragment>
<ListItem button onClick={handleClick}>
<ListItemIcon>{item.icon}</ListItemIcon>
<ListItemText primary={item.title} secondary={item.description} />
{open ? <ExpandLess /> : <ExpandMore />}
</ListItem>
<Collapse in={open} timeout="auto" unmountOnExit>
<List component="div" disablePadding>
{children.map((child, key) => (
<MenuItem key={key} item={child} />
))}
</List>
</Collapse>
</React.Fragment>
);
};

You shouldn't call a react hook inside of any function that is not a react component. Please see React Rules of Hooks
What you could do instead is pass setToggle directly into the Drawer component as a prop and do something like this for it's onClick attribute:
onClick={() => setToggle(<value>)}

Material-UI TextField loses focus on every onChange

I am creating the following component:
It will contain an array of objects, where each object is a prescription, with the medicine name from the select and a TextField for the Dosis.
My problem is that the TextField loses focus on every onChange() and is very frustrating because it cannot be edited on a single focus.
This is my component :
const MedicineSelect = ({ medications, setMedications, ...props }) => {
const { medicines } = useMedicines()
const classes = useStyles()
const handleChange = (index, target) => {
// setAge(event.target.value)
const newMedications = cloneDeep(medications)
newMedications[index][target.name] = target.value
setMedications(newMedications)
}
const handleAddMedicine = () => {
const newMedications = cloneDeep(medications)
newMedications.push({ medicine: '', dosis: '', time: '' })
setMedications(newMedications)
}
const handleDeleteMedicine = (index) => {
console.log('DELETE: ', index)
const newMedications = cloneDeep(medications)
newMedications.splice(index, 1)
setMedications(newMedications)
}
return (
<Paper style={{ padding: 5 }}>
<List>
{medications.map((medication, index) => (
<ListItem key={nanoid()} divider alignItems='center'>
<ListItemIcon>
<Tooltip title='Eliminar'>
<IconButton
className={classes.iconButton}
onClick={() => handleDeleteMedicine(index)}
>
<HighlightOffOutlinedIcon />
</IconButton>
</Tooltip>
</ListItemIcon>
<FormControl className={classes.formControl}>
<InputLabel
id={`${index}-select-${medication}-label`}
>
Medicamento
</InputLabel>
<Select
labelId={`${index}-select-${medication}-label`}
id={`${index}-select-${medication}`}
name='medicine'
value={medication.medicine}
onChange={(event) =>
handleChange(index, event.target)
}
>
{medicines.map((medicine) => (
<MenuItem
key={nanoid()}
value={medicine.name}
>
{medicine.name}
</MenuItem>
))}
</Select>
</FormControl>
<TextField
// fullWidth
id={`${index}-text-${medication}`}
label='Dosis'
name='dosis'
onChange={(event) =>
handleChange(index, event.target)
}
value={medication.dosis}
/>
</ListItem>
))}
<Button onClick={handleAddMedicine}>+ agregar</Button>
</List>
</Paper>
)
}
And here is where I set the component:
const [medications, setMedications] = useState([
{ medicine: '', dosis: '', time: '' },
])
...
<Grid item md={12} xs={12}>
<Accordion>
<AccordionSummary
expandIcon={<ExpandMoreIcon />}
aria-controls='panel1a-content'
id='panel1a-header'
>
<Typography variant='h4'>
Tratamiento:
</Typography>
</AccordionSummary>
<AccordionDetails>
<Container disableGutters>
<MedicineSelect
medications={medications}
setMedications={setMedications}
/>
</Container>
</AccordionDetails>
</Accordion>
</Grid>
...
Adding and removing objects from the array works perfect. selecting the medicine from the select, also works perfect. the only problem I have is when editing the Dosis TextField, with every character, the focus is lost and I have to click again on the TextField.
Please help me getting this fixed!!!

After searching a lot, finally I found the solution. Actually when using nanoid() to create unique keys, on every state update React re-renders all components and since the id of both the List and the TextField component are regenerated by nanoid on every render, React loses track of the original values, that is why Focus was lost.
What I did was keeping the keys unmuttable:
<ListItem key={`medication-${index}`} divider alignItems='center'>
and
<TextField
key={`dosis-${index}`}
fullWidth
// id={`${index}-dosis-${medication}`}
label='Dosis'
name='dosis'
onChange={(event) =>
handleChange(index, event.target)
}
value={medication.dosis}
/>

limit the number of suggestions AutoComplete component

I've been looking at the (https://material-ui.com/api/autocomplete/) API for the autocomplete component but I can't seem to find a way (from my limited knowledge of javascript) to only display a certain number of options below the TextField.
I'm trying to incorporate a search function with over 7,000 data but I don't want to display all of it at once. How can I limit the options to at most 10 suggestions?

This can be done using filterOptions prop and createFilterOptions function.
...
import { Autocomplete, createFilterOptions } from "#material-ui/lab";
const OPTIONS_LIMIT = 10;
const defaultFilterOptions = createFilterOptions();
const filterOptions = (options, state) => {
return defaultFilterOptions(options, state).slice(0, OPTIONS_LIMIT);
};
function ComboBox() {
return (
<Autocomplete
filterOptions={filterOptions}
id="combo-box-demo"
options={top100Films}
getOptionLabel={(option) => option.title}
style={{ width: 300 }}
renderInput={(params) => (
<TextField {...params} label="Combo box" variant="outlined" />
)}
/>
);
}
GitHub issue

Ciao, you could use filterOptions as explained by #bertdida or you could directly filter options array in this way:
const ELEMENT_TO_SHOW = 10;
...
<Autocomplete
id="combo-box-demo"
options={top100Films.filter((el, i) => { // here add a filter for options
if (i < ELEMENT_TO_SHOW) return el;
})}
getOptionLabel={(option) => option.title}
style={{ width: 300 }}
renderInput={(params) => (
<TextField {...params} label="Combo box" variant="outlined" />
)}
/>
Here a codesandbox example.

I started with bertida's answer but then I found out createFilterOptions can do it already (see https://material-ui.com/components/autocomplete/#createfilteroptions-config-filteroptions for other interesting options)
const OPTIONS_LIMIT = 10;
const filterOptions = createFilterOptions({
limit: OPTIONS_LIMIT
});
function ComboBox() {
return (
<Autocomplete
filterOptions={filterOptions}
id="combo-box-demo"
options={top100Films}
getOptionLabel={(option) => option.title}
style={{ width: 300 }}
renderInput={(params) => (
<TextField {...params} label="Combo box" variant="outlined" />
)}
/>
);
}
