# shadcn/ui Forms

Build validated forms with react-hook-form, zod, and shadcn/ui components.

## Setup

### Install Dependencies

```bash
npm install react-hook-form zod @hookform/resolvers
npx shadcn@latest add form input label
```

### Form Component Overview

shadcn's Form component wraps react-hook-form with accessible form fields:

- `Form` - FormProvider wrapper
- `FormField` - Controller wrapper
- `FormItem` - Field container
- `FormLabel` - Accessible label
- `FormControl` - Input wrapper
- `FormDescription` - Helper text
- `FormMessage` - Error message

## Basic Form Pattern

### 1. Define Zod Schema

```tsx
import { z } from "zod"

const formSchema = z.object({
  username: z.string().min(2, "Username must be at least 2 characters"),
  email: z.string().email("Invalid email address"),
  password: z.string().min(8, "Password must be at least 8 characters"),
})

type FormValues = z.infer<typeof formSchema>
```

### 2. Create Form Component

```tsx
"use client"

import { zodResolver } from "@hookform/resolvers/zod"
import { useForm } from "react-hook-form"
import { Button } from "@/components/ui/button"
import {
  Form,
  FormControl,
  FormDescription,
  FormField,
  FormItem,
  FormLabel,
  FormMessage,
} from "@/components/ui/form"
import { Input } from "@/components/ui/input"

export function SignupForm() {
  const form = useForm<FormValues>({
    resolver: zodResolver(formSchema),
    defaultValues: {
      username: "",
      email: "",
      password: "",
    },
  })

  async function onSubmit(data: FormValues) {
    console.log(data)
    // Handle form submission
  }

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-6">
        <FormField
          control={form.control}
          name="username"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Username</FormLabel>
              <FormControl>
                <Input placeholder="johndoe" {...field} />
              <
