I'm using react-select library and I'm calling the function in the options and that function takes one parameter. But when countryCode state is updated, it does not update in select tag.
When I pass hardcoded value in the function like options={getSortedState("US")}, it works fine but when I get value from API and set state of parameter then it does not work.
<Controller
control={control}
name="options"
render={({ field }) => (
<Select
value={field.value}
options={getSortedState(countryCode)}
onChange={(state) => field.onChange(state)}
placeholder="Select State"
defaultValue={field.value}
onInputChange={() => {
console.log('A', countryCode);
setCountryCode('');
setCountryCode(countryCode);
}}
// options={getLiDepartments()}
/>
)}
/>

I'm curious if anyone has used conditional fields in react-hook-from but within a map function. I've got the basic rendering happening, but since it is in a list and they all refer to the same .map() criteria, it is populating the conditional input for all fields, regardless if they are checked. Heres the basic idea for using conditional fields in RHF: https://codesandbox.io/s/react-hook-form-conditional-fields-qgr41
Heres what I've got so far:
{goals && goals.map((goal) => (
<>
<FormControlLabel
control={
<Switch
key={goal.title}
//id..? marked? title?
{...register('marked')}
name='marked'
value={goal.marked}
/>}
label={goal.title}
/>
<br />
{marked && (
<>
<Input
key={goal.title}
{...register('goal.note')}
id="note"
type='text'
label="Progress Note"
name="note"
onChange={(e) => {
e.target.value = e.target.value
}}
/>
<br />
</>
) }
The problem is that from the UI side, when I toggle the switch (or mark a checkbox), that all the fields populated in the map are referring to the same prop in the switch, 'marked'. So when toggling for 1, it populates the additional input field for all elements in the map function.
An additional issue I have yet to look into is passing the data for the individual fields to the data collected by the form for the submit. Right now, my assumption is that all fields would be treated as one value, since the form is recognizing them all together. So ideally if one item in the map is toggled and additional info is provided, then only those values are passed to the form for the submit, rather than all fields (toggled or not) being passed.
UPDATE
So I got the toggle functioning by creating a child component in order to more easily manage the state of the toggle, and leveraging the index within the props so the browser would not treat each conditional field as the same:
parent component:
{goals && goals.map((goal, index) => (
<GoalInput
goal={goal}
index={index}
register={register}
control={control}
errors={errors}
/>
new child component:
function GoalInput({ goal, index, register, control, errors }) {
const [toggle, setToggle] = useState(false)
return (
<>
<FormControlLabel
control={
<Switch
key={index}
{...register(`goals.${index}.marked`)}
checked={toggle}
name={`goals.${index}.marked`}
value={toggle}
onChange={() => setToggle(!toggle)}
/>
}
label={goal.title}
/>
<br />
{toggle ? (
<>
<Controller
control={control}
name={`goals.${index}.note`}
id={`goals.${index}.note`}
render={({field}) => (
<Input
type='text'
index={index}
error={!!errors.note}
value={field.value}
onChange={(e)=>field.onChange(e)}
label="Progress Note"
/>
)}
/>
<br />
</>
) : <></>}
</>
)
}
So the toggles work independently, appropriately record whether the value of the toggle is true/false, and the subsquent conditional input in being tracked as well. Still have some struggles with the data being passed correctly through to the backend, but that is another issue. Hope this helps anyone coming along.
I am not able to code in the right way such that formik.values will reflect into Material UI's Checkbox
Checkboxes are a little tricky to include in third party forms packages, and Material UI doesn't help with that either.
What you need to do is use the FormControlLabel component to handle the onChangge event that formik needs. Then on the Checkbox you just set the checked prop to be whatever formik has in its values.
Here is an example I use for a Checkbox to set an isAdmin value.
const formik = useFormik({
initialValues:{
isAdmin: false
},
});
<FormControlLabel
control={<Checkbox checked={formik.values.isAdmin} />}
label="is Admin"
name="isAdmin"
onChange={formik.handleChange}
/>
Using 'as'
Use the as prop with Formik Field and pass any props required to the Field itself. It will pass them onto FormControlLabel. For example, here the label field is passed down to FormControlLabel:
<Field
type="checkbox"
name="myFormikName"
as={FormControlLabel}
control={<Checkbox />}
label="This will trigger my formik name field"
/>
Multiple checkboxes using 'as'
If you have multiple checkboxes with the same name (array) you need to pass the "checked" value like so. Checks if the Formik 'name' array includes the name.
const { values } = useFormikContext()
render (
{names?.map(name => (
<Field
type="checkbox"
name="names"
value={name.fullName}
key={name.id}
as={FormControlLabel}
control={<Checkbox/>}
checked={values.names.includes(name.fullName)}
label={name.fullName}
/>
))}
)
Using 'setFieldValue'
const { values, setFieldValue } = useFormikContext()
<FormControlLabel
control={<Checkbox />}
label="My mui label"
checked={values.myMuiCheck}
onChange={() =>
setFieldValue(
'myMuiCheck',
!values.myMuiCheck,
)
}
/>
I'm trying to use a react-select component inside of a form created using react-hook-form. I have followed the instructions from the react-hook-form website here, but when I submit the form the value from the select component is "" (the default value).
I know that the form is working in general because other values that are input with ref={register} work fine. It's just this one value that I'm using the Controller for. Am I missing a prop in the Select component or am I going wrong somewhere else?
I have a parent component where the form is defined:
<Form id="public-share-form" onSubmit={handleSubmit(onSubmit)}>
<Controller
as={<PublicShareNetworkSelect />}
name="network"
control={control}
defaultValue=""
/>
</Form>
Then a child component for the react-select component used in the as prop of the Controller:
return (
<Select
closeMenuOnSelect={true}
options={networks}
noOptionsMessage={() => "No matching options"}
defaultValue=""
className="basic-single"
classNamePrefix="select"
/>
);
I think you need to use Select directly like this:
<Controller
as={
<Select
closeMenuOnSelect={true}
options={networks}
noOptionsMessage={() => "No matching options"}
defaultValue=""
className="basic-single"
classNamePrefix="select"
/>
}
name="network"
control={control}
defaultValue=""
/>
I'm using the react-datepicker inside the react-final-form. I'm using a template with multiple steps https://codesandbox.io/s/km2n35kq3v?file=/index.js. The problem is that I'm not able to integrate the datepicker inside the component. My Code looks like this:
return (
<Field name={props.name} parse={() => true}>
{props => (
<DatePicker
locale="de"
placeholderText="Datum eingeben"
selected={startDate}
dateFormat="P"
openToDate={new Date()}
minDate={new Date()}
disabledKeyboardNavigation
name={props.name}
value={startDate}
onChange={(date) => setStartDate(date)}
/>
)}
</Field>
);
Does anyone knows how I can use it so the data gets passed at the end of the form?
Best regards
I used the wizard form example you sent and added DatePicker similar to yours.
Check the wizard example
But basically, I changed your onChange method to actually use react-final-form field props. Now, it uses this.props.input.onChange, which updates the final form state value, and used this.props.input.value to set the selected state (you can then load initial values into final form):
const RenderDatePicker = ({ name, input, input: { value, onChange } }) => {
return (
<DatePicker
locale="de"
placeholderText="Datum eingeben"
dateFormat="P"
selected={value && isValid(value) ? toDate(value) : null} // needs to be checked if it is valid date
disabledKeyboardNavigation
name={name}
onChange={(date) => {
// On Change, you should use final-form Field Input prop to change the value
if (isValid(date)) {
input.onChange(format(new Date(date), "dd-MM-yyyy"));
} else {
input.onChange(null);
}
}}
/>
);
};
<div>
<label>Date of birth</label>
<Field
name="dateOfBirth"
component={RenderDatePicker}
validate={required}
/>
<Error name="dateOfBirth" />
</div>
Hopefully this helps you.
Solution
I used renderTags in my Autocomplete:
renderTags={() => (
<div>
{(props.selectedAutocompleteValues).map(value => (
<Chip key={value} label={value} />
))}
</div>
)}
Original question
I'm trying to add a handler that clears all selected values from an Autocomplete with multiple values and a dropdown. Basicly duplicating the action of the clear-button that is inside the Autocomplete, and triggering this action from outside the Autocomplete.
The reason for this is that I want to have a filter (material-ui Select) that allows reduces the number of options in the Autocomplete. When changing the filter-value, the previously selected values of the Autocomplete should be cleared.
I'm rendering the values in the Autocomplete with the following code, so it seems like what I need to do is change the params in some way. Any suggestions on how to do this, or other ways of clearing the values?
renderInput={params => (
<TextField {...params} label="my-label" variant="outlined" fullWidth />
)}
Update after comment from Ryan Cogswell:
<Autocomplete
multiple
disableCloseOnSelect
autoHighlight
clearText='Nullstill'
closeText='Lukk'
openText='Åpne'
options={Array.from(props.myMap.keys())}
onChange={(event: any, value: string) => {
props.myUpdateFunction(value)
}}
renderInput={params => (
<TextField {...params} label="myLabel" variant="outlined" fullWidth />
)}
/>
where myUpdateFunction is in the grandparent-component of where the Autocomplete is:
myUpdateFunction = (myArray: Array<string>) => {
this.setState({
selectedAutocompleteValues: myArray,
})
}
The Select component that I want to use to reset the Autocomplete component:
<Select
labelId="my-select-label"
id="my-select"
autoWidth
value={props.mySelectValue}
onChange={(event: any) => props.updateSelect(event.target.value)}>
{Array.from(props.selectOptions, ([optionNr, optionName]) =>
<MenuItem key={optionNr} value={optionNr}>{optionName}</MenuItem>
)}
</Select>
with the following onChange handler:
updateFylke = (value: number) => {
const selectedAutocompleteValues = new Array<string>();
this.setState({
mySelectValue: value,
selectedAutocompleteValues: selectedAutocompleteValues,
})
}
I recommend using a controlled input approach (i.e. specify the value prop for the Autocomplete using selectedAutocompleteValues). Then clearing the Autocomplete is just a matter of updating your state appropriately.
You can see an example of this approach in this related answer: Material ui Autocomplete: can tags be created on events aside from 'Enter' events?.
