this is the example form using shadcn and react form hook

"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 {
  Select,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@/components/ui/select"
import { Textarea } from "./ui/textarea"

const FormSchema = z.object({
  welcomeChannel: z.string(),
  welcomeMessage: z.string(),
})

export default function WelcomeForm() {
  const form = useForm<z.infer<typeof FormSchema>>({
    resolver: zodResolver(FormSchema),
  })

  function onSubmit(data: z.infer<typeof FormSchema>) {
    console.log(data)
  }

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)}>
        <FormField
          control={form.control}
          name="welcomeChannel"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Welcome channel</FormLabel>
              <Select onValueChange={field.onChange} defaultValue={field.value}>
                <FormControl>
                  <SelectTrigger>
                    <SelectValue placeholder="Select a channel" />
                  </SelectTrigger>
                </FormControl>
                <SelectContent>
                  <SelectItem value="123">Channel 1</SelectItem>
                  <SelectItem value="234">Channel 2</SelectItem>
                  <SelectItem value="345">Channel 3</SelectItem>
                </SelectContent>
              </Select>
              <FormDescription>
                The channel where the welcome message will be sent
              </FormDescription>
              <FormMessage />
            </FormItem>
          )}
        />

        <FormField
          control={form.control}
          name="welcomeMessage"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Welcome message</FormLabel>
              <FormControl>
                <Textarea
                  placeholder="Message"
                  className="resize-none"
                  {...field}
                />
              </FormControl>
              <FormDescription>
                The message that will be sent to the welcome channel
              </FormDescription>
              <FormMessage />
            </FormItem>
          )}
        />
        <Button type="submit">Save</Button>
      </form>
    </Form>
  )
}

and for example i would like to take out the Select part to another file so i can reuse it

would i take out the whole FormField tag and pass form as props so i can set the control={form.control} or would i rather take out the FormItem and pass in as props the field given in render
