i haven't tried. But I need this once I submit the form, I need to clear all field values. Now am manually setting all field values to default values.

I have similar issue. Using this force refresh did the trick. But it's not pretty.

"use client";

import { zodResolver } from "@hookform/resolvers/zod";
import { useForm } from "react-hook-form";
import { z } from "zod";

import { Button } from "../../../components/ui/button";
import {
  Form,
  FormControl,
  FormDescription,
  FormField,
  FormItem,
  FormLabel,
  FormMessage,
} from "../../../components/ui/form";
import { RadioGroup, RadioGroupItem } from "../../../components/ui/radio-group";
import { useTheme } from "next-themes";
import {useEffect} from "react";

const appearanceFormSchema = z.object({
  theme: z.enum(["light", "dark", "system"], {
    required_error: "Please select a theme.",
  }),
});

type AppearanceFormValues = z.infer<typeof appearanceFormSchema>;

export function AppearanceForm() {
  const { setTheme, theme } = useTheme();
  let forceRefresh = new Date().getTime();

  const form = useForm<AppearanceFormValues>({
    resolver: zodResolver(appearanceFormSchema)
  });

  useEffect(() => {
    form.resetField('theme', {defaultValue: theme as 'light' | 'dark' | 'system' ?? 'light'});
    forceRefresh = new Date().getTime();
  }, [theme, form.reset]);

  function onSubmit(data: AppearanceFormValues) {
    setTheme(data.theme);
  }

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-8">
        <FormField key={forceRefresh}

@saravanakumarputta can u pls provide code that help us to understand where is issue?

[kam-st]

It is not a bug. It usually happens if you don't set default values in your useForm function.

You need to set default values to empty for each field to reset form.
