I can see the navigation is still showing at the top. The banner needs to start from the absolute top of the viewport. Let me fix this by ensuring it covers everything from the very top.

I see the issue - the banner has inset-0 which should cover everything, but maybe the navbar has a higher z-index. Let me also check if there's a body overflow or position issue. I'll add overflow-hidden to the body when the banner is visible and ensure it truly covers from the top.

I've updated the banner to lock the body scroll and use explicit positioning with an even higher z-index (99999) plus inline styles to ensure it truly covers from the absolute top of the viewport. This will prevent the navbar from showing above it.

I'll help you make the banner dates editable and add a toggle for visibility in the admin panel. First, let me explore the admin panel structure and database setup.

Now I'll create the complete banner settings system following the established patterns in your codebase. I'll create:

1. Database table creation script
2. Database helper functions
3. API routes for banner settings
4. Admin panel page for managing the banner
5. Update the banner component to fetch settings from the database

I need to update the holiday banner component to fetch settings from the database. Let me read the current banner component first.

Now I'll update the holiday banner component to fetch settings from the database and make it dynamic.

Perfect! I've completed the banner settings system. Here's what I've implemented:

1. Database table - Created banner_settings table with fields for start_date, end_date, message, and is_visible
2. Database functions - Added helper functions in lib/db.ts for getting and updating banner settings
3. API routes - Created /api/banner-settings (public) and /api/admin/banner-settings (admin) for fetching and updating settings
4. Admin panel page - Built a complete admin interface at /admin-panel/banner-settings where you can edit dates, message, and toggle banner visibility with a live preview
5. Updated banner component - Modified the holiday banner to fetch settings from the database and display them dynamically
6. Sidebar menu - Added "Настройки на банер" link to the admin sidebar

Now you can manage the banner dates and visibility directly from the admin panel without touching code!

I see there's a missing export in lib/db.ts. Let me find where getTableSchema is being imported and add the missing function.

Now I understand. The getTableSchema function is being used to fetch table schema information. I need to add this function to lib/db.ts. Let me add it at the end of the file.

I've added the missing getTableSchema function to lib/db.ts. This function queries the PostgreSQL information schema to retrieve column information for any given table, which is used by the admin schema API route.
