Park Search Implementation

Search Flow

1. Quick Search (Suggestions)

   • Endpoint: suggest_parks/
   • Shows up to 8 suggestions
   • Uses HTMX for real-time updates
   • 300ms debounce for typing

2. Full Search

   • Endpoint: parks:park_list
   • Shows all matching results
   • Supports view modes (grid/list)
   • Integrates with filter system

Implementation Details

Frontend Components

• Search input using built-in HTMX and Alpine.js

  <div x-data="{ query: '', selectedId: null }"
       @search-selected.window="...">
    <form hx-get="..." hx-trigger="input changed delay:300ms">
      <!-- Search input and UI components -->
    </form>
  </div>
  

• No custom JavaScript required
• Uses native frameworks' features for:
  • State management (Alpine.js)
  • AJAX requests (HTMX)
  • Loading indicators
  • Keyboard interactions

Templates

• park_list.html: Main search interface
• park_suggestions.html: Partial for search suggestions
• park_list_item.html: Results display

Key Features

• Real-time suggestions
• Keyboard navigation (ESC to clear)
• ARIA attributes for accessibility
• Dark mode support
• CSRF protection
• Loading states

Search Flow

1. User types in search box
2. After 300ms debounce, HTMX sends request
3. Server returns suggestion list
4. User selects item
5. Form submits to main list view with filter
6. Results update while maintaining view mode
