Subject: [PATCH 1/4] Update index.tsx Add Search Functionality to Dropdown
 Component

This PR introduces a searchable dropdown component to enhance user experience when selecting from a large list of options. The new functionality allows users to:

1. Search within the dropdown options using a text input
2. Filter options dynamically as they type
3. Select an option either by typing or clicking
4. Maintain accessibility standards with keyboard navigation

Key Changes:
- Added a search input field above the dropdown options
- Implemented real-time filtering based on user input
- Enhanced styling for better visibility of search results
- Maintained backward compatibility with existing prop interfaces
- Added unit tests for search functionality
