Sticky Not Working? Here's What's Likely Breaking It

1. overflow-hidden is Killing Sticky Behavior

One of the most common reasons position: sticky stops working is because one of the parent elements has overflow: hidden. In your case, it looks like the SidebarProvider is the culprit:

<SidebarProvider className="overflow-hidden"> // ❌ This prevents sticky from working

🛠 Fix: Either remove the class or change it to overflow-visible:

<SidebarProvider className="overflow-visible"> 

2. Other Parent Containers Might Be Causing Trouble

Even if your sticky element has the right styles, it won't work if any of its ancestors (like SidebarInset) have overflow set in a way that clips content:

<SidebarInset className="overflow-auto"> // ❌ This could also break sticky

Try removing or adjusting this as well — especially if you don’t need scrolling on that container.

3. Fixed Headers Can Mess with Sticky Calculations

If you’re using a fixed header like:

<TopNav className="fixed top-0 w-full" /> 

...then sticky elements might not behave as expected because the page’s layout shifts. You’ll need to account for the height of the fixed header when using top-XX values.

Suggested Fix (Cleaned-Up Layout)

Here’s a cleaner version of your layout with the sticky-breaking styles removed:

<SidebarProvider> {/* Remove overflow-hidden */}
  <AppSidebar />
  <SidebarInset> {/* Remove overflow-auto if not needed */}
    <TopNav />
    <BannerMessage />
    <main className="flex min-h-[100dvh-4rem] justify-center">
      <div className="container max-w-screen-2xl p-3 pb-4 lg:p-6 lg:pb-10">
        {children}
      </div>
    </main>
  </SidebarInset>
</SidebarProvider>
