Material-UI Select with React Hook Form

My experience with React hook Form (RHF) is amazing so far. When you are using external css libraries with react hook form, you have to make few adjustments for example in place of ref, you have to use inputRef to pass the register method of RHF.

In this post, I would like to share a solution to the problem of adding validation to Select component of Material-UI* with RHF. Implementing select box is not hard. You can do that with TextField and also with Select component of Material-UI but adding validation can give you a headache.

This is solution I implemented for adding select box with validations.

<Controller
  as={
    <Select>
     {options.map((option, index) => (
      <MenuItem key={index} value={option}>
        {option}
      </MenuItem>
     ))}
    </Select>
    }
  name={options_name}
  control={control}
  defaultValue=""
  rules={{ required: true }
/>

So validation worked for me by adding the following attribute to the controller.

rules={{ required: true }}

I hope this will be helpful.
