+
+## Form Patterns
+
+### Basic Form Setup
+```tsx
+import { useForm } from "react-hook-form"
+import { zodResolver } from "@hookform/resolvers/zod"
+import * as z from "zod"
+import {
+  Form,
+  FormControl,
+  FormDescription,
+  FormField,
+  FormItem,
+  FormLabel,
+  FormMessage,
+} from "@/components/ui/form"
+
+const formSchema = z.object({
+  username: z.string().min(2, {
+    message: "Username must be at least 2 characters.",
+  }),
+  email: z.string().email({
+    message: "Please enter a valid email address.",
+  }),
+  bio: z.string().max(160).optional(),
+})
+
+export function ProfileForm() {
+  const form = useForm<z.infer<typeof formSchema>>({
+    resolver: zodResolver(formSchema),
+    defaultValues: {
+      username: "",
+      email: "",
+      bio: "",
+    },
+  })
+
+  async function onSubmit(values: z.infer<typeof formSchema>) {
+    try {
+      // Submit to API
+      await submitForm(values)
+    } catch (error) {
+      form.setError("root", {
+        message: "Something went wrong. Please try again.",
+      })
+    }
+  }
+
+  return (
+    <Form {...form}>
+      <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-8">
+        <FormField
+          control={form.control}
+          name="username"
+          render={({ field }) => (
+            <FormItem>
+              <FormLabel>Username</FormLabel>
+              <FormControl>
+                <Input placeholder="johndoe" {...field} />
+              </FormControl>
+              <FormDescription>
+                This is your public display name.
+              </FormDescription>
+              <FormMessage />
+            </FormItem>
+          )}
+        />
+        <Button type="submit" disabled={form.formState.isSubmitting}>
+          {form.formState.isSubmitting ? "Submitting..." : "Submit"}
+        </Button>
+      </form>
+    </Form>
+  )
+}
+```
+
+### Complex Validation
+```tsx
+const formSchema = z.object({
+  password: z.string()
+    .min(8, "Password must be at least 8 characters")
+    .regex(/[A-Z]/, "Password must contain an uppercase letter")
+    .regex(/[a-z]/, "Password must contain a lowercase letter")
+    .regex(/[0-9]/, "Password must contain a number"),
+  confirmPassword: z.string(),
+  age: z.coerce.number()
+    .min(18, "You must be at least 18 years old")
+    .max(100, "Please enter a valid age"),
+  website: z.string().url().optional().or(z.literal("")),
+  terms: z.boolean().refine((val) => val === true, {
+    message: "You must accept the terms and conditions",
+  }),
+}).refine((data) => data.password === data.confirmPassword, {
+  message: "Passwords don't match",
+  path: ["confirmPassword"],
+})
+```
+
+### Dynamic Fields
+```tsx
+import { useFieldArray } from "react-hook-form"
+
+const formSchema = z.object({
+  items: z.array(z.object({
+    name: z.string().min(1, "Required"),
+    quantity: z.coerce.number().min(1),
+    price: z.coerce.number().min(0),
+  })).min(1, "Add at least one item"),
+})
+
+export function DynamicForm() {
+  const form = useForm<z.infer<typeof formSchema>>({
+    resolver: zodResolver(formSchema),
+    defaultValues: {
+      items: [{ name: "", quantity: 1, price: 0 }],
+    },
+  })
+
+  const { fields, append, remove } = useFieldArray({
+    control: form.control,
+    name: "items",
+  })
+
+  return (
+    <Form {...form}>
+      <form onSubmit={form.handleSubmit(onSubmit)}>
+        {fields.map((field, index) => (
+          <div key={field.id} className="flex gap-4">
+            <FormField
+              control={form.control}
+              name={`items.${index}.name`}
+              render={({ field }) => (
+                <FormItem>
+                  <FormControl>
+                    <Input {...field} />
+                  </FormControl>
+                  <FormMessage />
+                </FormItem>
+              )}
+            />
+            <Button
+              type="button"
+              variant="destructive"
+              onClick={() => remove(index)}
+            >
+              Remove
+            </Button>
+          </div>
+        ))}
+        <Button
+          type="button"
+          variant="outline"
+          onClick={() => append({ name: "", quantity: 1, price: 0 })}
+        >
+          Add Item
+        </Button>
+      </form>
+    </Form>
+  )
+}
+```
+
+### Async Validation
+```tsx
+const formSchema = z.object({
+  username: z.string().min(3),
+})
+
+export function AsyncValidationForm() {
+  const form = useForm<z.infer<typeof formSchema>>({
+    resolver: zodResolver(formSchema),
+  })
+
+  const checkUsername = async (username: string) => {
+    const response = await fetch(`/api/check-username?username=${username}`)
+    const { available } = await response.json()
+    if (!available) {
+      form.setError("username", {
+        type: "manual",
+        message: "Username is already taken",
+      })
+    }
+  }
+
+  return (
+    <FormField
+      control={form.control}
+      name="username"
+      render={({ field }) => (
+        <FormItem>
+          <FormControl>
+            <Input
+              {...field}
+              onBlur={async (e) => {
+                field.onBlur()
+                await checkUsername(e.target.value)
+              }}
+            />
+          </FormControl>
+          <FormMessage />
+        </FormItem>
+      )}
+    />
+  )
+}
+```
+
+### File Upload
+```tsx
+const formSchema = z.object({
+  avatar: z
+    .custom<FileList>()
+    .refine((files) => files?.length === 1, "Image is required")
+    .refine(
+      (files) => files?.[0]?.size <= 5000000,
+      "Max file size is 5MB"
+    )
+    .refine(
+      (files) => ["image/jpeg", "image/png"].includes(files?.[0]?.type),
+      "Only .jpg and .png formats are supported"
+    ),
+})
+
+<FormField
+  control={form.control}
+  name="avatar"
+  render={({ field: { onChange, value, ...rest } }) => (
+    <FormItem>
+      <FormLabel>Avatar</FormLabel>
+      <FormControl>
+        <Input
+          type="file"
+          accept="image/*"
+          onChange={(e) => onChange(e.target.files)}
+          {...rest}
+        />
+      </FormControl>
+      <FormDescription>
+        Upload your profile picture (max 5MB)
+      </FormDescription>
+      <FormMessage />
+    </FormItem>
+  )}
+/>
+```
+
+## Form Components
+
+### Custom Select
+```tsx
+<FormField
+  control={form.control}
+  name="country"
+  render={({ field }) => (
+    <FormItem>
+      <FormLabel>Country</FormLabel>
+      <Select onValueChange={field.onChange} defaultValue={field.value}>
+        <FormControl>
+          <SelectTrigger>
+            <SelectValue placeholder="Select a country" />
+          </SelectTrigger>
+        </FormControl>
+        <SelectContent>
+          <SelectItem value="us">United States</SelectItem>
+          <SelectItem value="uk">United Kingdom</SelectItem>
+        </SelectContent>
+      </Select>
+      <FormMessage />
+    </FormItem>
+  )}
+/>
+```
+
+### Checkbox Group
+```tsx
+const items = [
+  { id: "react", label: "React" },
+  { id: "vue", label: "Vue" },
+  { id: "angular", label: "Angular" },
+]
+
+<FormField
+  control={form.control}
+  name="frameworks"
+  render={() => (
+    <FormItem>
+      <FormLabel>Frameworks</FormLabel>
+      {items.map((item) => (
+        <FormField
+          key={item.id}
+          control={form.control}
+          name="frameworks"
+          render={({ field }) => (
+            <FormItem className="flex items-center space-x-2">
+              <FormControl>
+                <Checkbox
+                  checked={field.value?.includes(item.id)}
+                  onCheckedChange={(checked) => {
+                    return checked
+                      ? field.onChange([...field.value, item.id])
+                      : field.onChange(
+                          field.value?.filter((value) => value !== item.id)
+                        )
+                  }}
+                />
+              </FormControl>
+              <FormLabel className="font-normal">
+                {item.label}
+              </FormLabel>
+            </FormItem>
+          )}
+        />
+      ))}
+      <FormMessage />
+    </FormItem>
+  )}
+/>
+```
+
+## Best Practices
+
+1. **Always validate on both client and server**
+2. **Use progressive enhancement** for no-JS support
+3. **Provide clear error messages**
+4. **Show loading states** during submission
+5. **Handle network errors** gracefully
+6. **Debounce async validations**
+7. **Save form state** for long forms
+8. **Use proper semantic HTML**
+
+Remember: Forms should be intuitive, accessible, and resilient!
