Build a custom header in GraphCommerce

Previously, you created a GraphCommerce app and started building your custom storefront with GraphCommerce. You're now ready to build a custom header for your app.

In this tutorial, you'll accomplish a series of tasks to add some specific functionality to your app. Your final app will be simple, but you'll learn where to find resources to build more complex features on your own.

After you've finished this tutorial, you'll have accomplished the following:

• Edited the layout component to remove components
• Add a simplified search Icon button
• Make a local copy of the MenuFab component and update its imports

Requirements

You've familiarized yourself with React ↗, Next.js ↗, and Mui ↗. GraphCommerce is a frontend React framework that uses Next.js for server-side rendering.

    justifyContent: 'center',
    flexGrow: 1,
    pointerEvents: 'none',
  }}
>
  <Logo />
</Box>

• Remove the style={{...}} prop from both the <MotionDiv> components to remove the Fab scroll animation

• Remove const { opacity, scale, shadowOpacity } = useFabAnimation()

• Update all imports:

import {
  extendableComponent,
  responsiveVal,
