This commit introduces a new `BaseDropdown` component with search functionality and refactors the campaign listing page to utilize this new component and improve its layout.
The `BaseDropdown` component was significantly refactored from a native `<select>` element to a custom component built with `div` and `input` elements. This allows for:
- **Search functionality**: Users can now type to filter dropdown options.
- **Improved accessibility**: Custom handling of focus and keyboard navigation.
- **Enhanced styling**: More control over the visual appearance.
The campaign listing page (`src/pages/campaigns/index.tsx`) was updated to:
- Replace the previous dropdowns with the new `BaseDropdown` component.
- Adjust the layout of the header, search bar, and filter section for better responsiveness and visual appeal.
- Update the `VITE_API_URL` in `.env` to ensure a newline at the end of the file.
These changes enhance the user experience by providing a more interactive and user-friendly way to select options and navigate the campaign page.
- Added ProfileCard component to display user profile information.
- Created DashboardLayout for consistent layout structure.
- Defined Campaign and related types for campaign management.
- Developed CampaignDetailPage for viewing individual campaign details.
- Implemented CampaignsPage for listing and filtering campaigns.
- Enhanced DashboardPage with user profile fetching and navigation.
- Built RegisterPage for user profile registration and updates.
- Added user service for fetching and updating user profiles.
- Established campaigns service for managing campaign data and interactions.
- Updated routing constants and router configuration for new pages.
