I can see the issue. The floating-menu.tsx is trying to import FloatingMenu from @tiptap/react, but FloatingMenu is not exported from that package. It's actually a component that needs to be created using the useFloatingMenu hook or built manually. Let me check the tiptap documentation and fix this:

The issue is clear now. The code is incorrectly importing FloatingMenu from @tiptap/react, but that export doesn't exist. The floating menu functionality in the template is using a custom implementation. Let me fix the import to use the correct Tiptap export or remove the incorrect import:

Now I understand the issue. The floating-menu.tsx component is trying to import FloatingMenu from @tiptap/react, but that doesn't exist. The component is using useFloatingMenu hook functionality indirectly. The correct approach is to remove that incorrect import since the component is building the floating menu manually using React state and DOM positioning. Here's the fix:

I've fixed the issue by removing the incorrect FloatingMenu import from @tiptap/react. The component was trying to import something that doesn't exist in that package. I've restructured it to render a simple positioned dropdown menu that appears when the slash command is triggered. The menu will now display correctly without the import error. You can now preview the app and use the "/" command in the editor to see the floating menu in action.
