@Nakul727 , for this task, try to wrap the Navbar component and add a "isCollapsed" state or something. I just DM'd you an example UI that I like but feel free to do it differently

@Nakul727 this will prob be an end-app-side thing, implemented in the parent container of the navbar. Maybe work in the src/components/Page.js file to do this
