VistasHow to use MUI Select with react-hook-form?
I've built a form in React using MUI and React Hook Form. I'm trying to create a custom TextField element that works as a Select Input. I would like it to be an uncontrolled component with a Ref prop. I've tried to pass the inputRef prop as the MUI and React Hook Form docs recommend but with no success.
<TextField
id="id"
name="name"
select
native="true"
className={classes.textField}
label="label"
margin="normal"
variant="outlined"
inputRef={register({ required: "Choose one option" })}
error={!!errors.name}
>
<MenuItem value="">Choose one option</MenuItem>
<MenuItem value="3">03</MenuItem>
<MenuItem value="6">06</MenuItem>
<MenuItem value="9">09</MenuItem>
<MenuItem value="12">12</MenuItem>
<MenuItem value="16">16</MenuItem>
<MenuItem value="18">18</MenuItem>
</TextField>
One thing that I've found is that if I use the native select with ref, it works just fine.
Besides, I tried to change the inputRef prop to a SelectProps one but it didn't work too.

Using Select component from Material-ui with react hook form need you to implement custom logic with a Controller https://react-hook-form.com/api#Controller
Here is a reusable component that will hopefully simplify the code to use that Select component in your app:
import FormControl from "@material-ui/core/FormControl";
import InputLabel from "@material-ui/core/InputLabel";
import Select from "@material-ui/core/Select";
import { Controller } from "react-hook-form";
const ReactHookFormSelect = ({
name,
label,
control,
defaultValue,
children,
...props
}) => {
const labelId = `${name}-label`;
return (
<FormControl {...props}>
<InputLabel id={labelId}>{label}</InputLabel>
<Controller
as={
<Select labelId={labelId} label={label}>
{children}
</Select>
}
name={name}
control={control}
defaultValue={defaultValue}
/>
</FormControl>
);
};
export default ReactHookFormSelect;
You can use it in your app like this:
<ReactHookFormSelect
id="numero_prestacao"
name="numero_prestacao"
className={classes.textField}
label="Em quantas parcelas?"
control={control}
defaultValue={numero_prestacao || ""}
variant="outlined"
margin="normal"
>
<MenuItem value="">Escolha uma opção</MenuItem>
<MenuItem value="3">03 parcelas</MenuItem>
<MenuItem value="6">06 parcelas</MenuItem>
<MenuItem value="9">09 parcelas</MenuItem>
<MenuItem value="12">12 parcelas</MenuItem>
<MenuItem value="16">16 parcelas</MenuItem>
<MenuItem value="18">18 parcelas</MenuItem>
</ReactHookFormSelect>
Here is your codeSandBox updated with this component for the selects in the Information form:

Here my code that working, hope it can help, need to use setValue
<TextField
fullWidth
inputRef={register({
name: 'name',
})}
select
onChange={e => setValue('name', e.target.value, true)}
label={label}
defaultValue={defaultValue}
>
{options.map((option) => (
<MenuItem key={option.label} value={option.value}>
{option.label}
</MenuItem>
))}
</TextField>
Here using native select, do not need setValue, but value alway string
<TextField
fullWidth
select
SelectProps={{
native: true,
inputProps: { ref: register, name: 'name' }
}}
label={label}
defaultValue={defaultValue}
>
{options.map((option) => (
<option key={option.label} value={option.value}>
{option.label}
</option>
))}
</TextField>

This is an example that uses Material-UI with React hook form. You need to add the validation in 'inputRef' prop of TextField. Also you need to add 'onChange' function to keep the state updated. 'shouldValidate' will trigger the validation.
<TextField
select
name='city'
inputRef={register({ required: true })}
onChange={e => setValue('city', e.target.value, { shouldValidate: true })}
label="City"
defaultValue="">
{cityList.map((option, index) => (
<MenuItem key={index} value={option}>
{option}
</MenuItem>
))}
</TextField>
{errors.city && <ErrorText>City is required</ErrorText>}

When you using react-hook-form with material UI, you don´t need to use onChange and setState. Only use inputRef and all works!

Just need to pass the register to the Input Ref
<Select
variant="outlined"
name="reason"
inputRef={register({ required: true })}

RHF v7 update
Below is a minimal code example of MUI Select in a RHF form:
const { formState, getValues, watch, register, handleSubmit } = useForm();
const { errors } = formState;
<TextField
select
fullWidth
label="Select"
defaultValue=''
inputProps={register('currency', {
required: 'Please enter currency',
})}
error={errors.currency}
helperText={errors.currency?.message}
>
{currencies.map((option) => (
<MenuItem key={option.value} value={option.value}>
{option.label}
</MenuItem>
))}
</TextField>
