Hi @cosmic jasper. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, it seems like you're facing an issue where your entire page, including the menu, is re-rendering when you change sections of the form. This is causing unnecessary calls to your getMenu function.

One way to solve this issue is by using a layout pattern in Next.js. The layout pattern allows you to deconstruct a page into a series of components, many of which can be reused between pages. This means you can have the same navigation bar (or in your case, menu) on every page without it re-rendering every time you navigate to a different page or section.

Here's an example of a layout pattern in Next.js:

import Navbar from './navbar'
import Footer from './footer'
 
export default function Layout({ children }) {
 return (
 <>
 <Navbar />
 <main>{children}</main>
 <Footer />
 </>
 )
}

In this example, the Navbar and Footer components are reused across different pages. The children prop is where the unique content for each page goes. In your case, you could replace Navbar with your Menu component.

However, if you're facing issues with the entire page re-rendering when deployed to Vercel, but not locally, it might be a bug related to the specific version of Next.js you're using. There's a reported issue (https://github.com/vercel/next.js/issues/54934) on GitHub where a user experienced a similar problem.

If you're using dynamic routes and you want to avoid re-rendering the entire page, you might want to look into using getStaticPaths or generateStaticParams for pre-rendering dynamic paths at build time. This can help improve performance by reducing the amount of rendering that needs to be done when a user navigates to a different page or section.

Here's an example of how to use generateStaticParams in the app directory:

# 
export async function generateStaticParams() {
 return [{ id: '1' }, { id: '2' }]
}
 
async function getPost(params) {
 const res = await fetch(`<https://.../posts/${params.id}`>)
 const post = await res.json()
 
 return post
}
 
export default async function Post({ params }) {
 const post = await getPost(params)
 
 return <PostLayout post={post} />
}

In this example, generateStaticParams is used to define the dynamic paths that should be pre-rendered at build time. This can help reduce the amount of re-rendering that needs to be done when a user navigates to a different page or section.
