# Location Selector Component Implementation

## Overview
Implementation of the LocationSelectorComponent for the ThrillWiki location management system. This component will provide address search, coordinate selection, and location validation functionality, integrating with our existing GeocodeService.

## Requirements

### 1. Address Search
- Autocomplete search interface
- Integration with GeocodeService
- Search result display
- Error handling
- Loading states
- Input validation

### 2. Coordinate Selection
- Map-based point selection
- Direct coordinate input
- Coordinate validation
- Format standardization
- Precision control
- Bounds checking

### 3. Current Location
- Browser geolocation support
- Permission handling
- Accuracy reporting
- Fallback behavior
- Loading states
- Error handling

### 4. Validation Feedback
- Address verification
- Coordinate validation
- Visual feedback
- Error messages
- Success states
- Loading indicators

## Implementation Plan

### 1. Component Structure
```php
class LocationSelectorComponent extends Component
{
    // Search State
    public string $searchQuery = '';
    public array $searchResults = [];
    public bool $isSearching = false;
    public ?string $validationError = null;

    // Location State
    public ?float $latitude = null;
    public ?float $longitude = null;
    public ?string $formattedAddress = null;
    public bool $isValidLocation = false;

    // UI State
    public bool $showSearchResults = false;
    public bool $isLoadingLocation = false;
    public string $mode = 'search'; // search|coordinates|current
}
```

### 2. Features
- Debounced address search
- Real-time validation
- GeocodeService integration
- Event-based updates
- Progressive loading
- Error recovery

### 3. User Interface
- Search input field
- Results dropdown
- Validation messages
- Mode switcher
- Coordinate inputs
- Current location button
- Loading indicators
