Conditional validation on when the checkbox is checked.

[shankhadevpadam]

I have a field that will be validated if the checkbox is checked and not required if the checkbox is unchecked.

In the sandbox, a phone should be validated if I checked the checkbox but the form should be submitted if the checkbox is unchecked.

Since you are doing your conditionals on a yup schema using when, the isPhone should be a <Field> that exists in the form. You used the native input element which won't work.

Thanks @logaretm.

does this also work if you use the useField composable in difference input components?
