# Activity Admin Page - Map Enhancement

## 🎯 What Was Changed

Enhanced the **Admin → Aktivity (Události)** page with professional map tools, replacing the basic Mapy.com search with a full featured location system.

## ✅ Changes Made

### 1. **Replaced Mapy.com Search with MapLinkImporter**

**Before:**
- Basic text input with Mapy.com suggestions
- No visual feedback
- No coordinate extraction

**After:**
- ✅ **MapLinkImporter** tool (same as Setup page)
- ✅ Import from Google Maps, Mapy.cz, OpenStreetMap links
- ✅ Automatic coordinate extraction
- ✅ Visual confirmation

### 2. **Added Live Map Preview**

When coordinates are imported:
- ✅ Shows live map with event location
- ✅ Uses club colors for marker
- ✅ Displays event title and location
- ✅ 300px preview height
- ✅ Shows exact coordinates
- ✅ Cancel button to clear coordinates

### 3. **Improved UI Organization**

**New Section Structure:**
```
Místo konání
├── MapLinkImporter (import from URL)
├── Název místa / Adresa (text input + suggestions)
├── Typ (event type selector)
└── Map Preview (when coordinates available)
```

### 4. **Enhanced Location Input**

- Kept Mapy.com suggestions (still works)
- Added better placeholder text
- Better helper text
- Wider input field (flex 2 vs flex 1 for type)

---

## 🎨 How It Works

### Step 1: Import Coordinates (Optional but Recommended)

User can paste any map link:
```
Google Maps: https://maps.google.com/...
Mapy.cz: https://mapy.cz/...
OpenStreetMap: https://www.openstreetmap.org/...
```

**MapLinkImporter extracts:**
- Latitude
- Longitude
- Zoom level (optional)

### Step 2: Enter Location Name

User types the location name:
```
"Sportovní hala TJ Sokol"
"Fotbalové hřiště u ZŠ"
"Tělocvična Družba"
```

**Mapy.com suggestions still work** - autocomplete dropdown appears

### Step 3: Visual Verification

If coordinates imported:
- ✅ Map appears automatically
- ✅ Shows marker at exact location
- ✅ Marker uses club colors
- ✅ Displays event title + location
- ✅ Can verify correctness

### Step 4: Adjust if Needed

If location is wrong:
- Click "Zrušit souřadnice" button
- Try different map link
- Or just use location name without coordinates

## 📊 Location Options Comparison

| Method | Coordinates | Map Preview | Geocoding | Best For |
|--------|-------------|-------------|-----------|----------|
| **Import from URL** | ✅ Yes | ✅ Yes | Not needed | Precise locations |
| **Type location name** | ❌ No | ❌ No | ✅ Frontend* | Quick entry |
| **Mapy.com suggestions** | ❌ No | ❌ No | ✅ Frontend* | Popular places |

\* Frontend geocoding happens when event is displayed (EventLocationMap component)

## 🗺️ Map Preview Features

## 💡 Usage Recommendations

### For Precise Locations

1. **Find venue on Google Maps or Mapy.cz**
2. **Copy the URL**
3. **Paste into MapLinkImporter**
4. **Verify on preview map**
5. **Add location name** (will show to visitors)
6. **Save event**

**Example:**
```
Map URL: https://maps.google.com/...coords=50.0947,17.6997
→ Extracts: 50.0947, 17.6997
→ Map preview appears
→ Add name: "Fotbalové hřiště TJ Sokol Krnov"
→ Save
```

### For General Locations

1. **Type location name directly**
2. **Use Mapy.com suggestions if needed**
3. **Skip coordinates** (frontend will geocode)
4. **Save event**

**Example:**
```
Location: "Sportovní hala, Krnov"
→ No coordinates
→ No map preview
→ Frontend will geocode when displaying
→ Save
```

## 🎯 Benefits

### For Admins

1. **Visual Confirmation** - See exactly where event is
2. **Error Prevention** - Catch wrong locations before saving
3. **Professional Tools** - Same quality as Setup page
4. **Flexibility** - Can use coordinates OR just location name
5. **Club Branding** - Map uses club colors

### For Visitors

2. **Fallback Geocoding** - Works with just location name
3. **Consistent** - Same map style across site
4. **Club Colors** - Branded map markers

## 📝 Technical Details

### State Management

```typescript
// New state variables
const [locationLat, setLocationLat] = useState<number | undefined>(undefined);
const [locationLng, setLocationLng] = useState<number | undefined>(undefined);
```

### Map Preview Logic

```typescript
{locationLat && locationLng && (
  <ContactMap
    latitude={locationLat}
    longitude={locationLng}
    zoom={15}
    clubName={editing?.title || editing?.location}
    address={editing?.location}
    mapStyle={settingsQ.data?.map_style || 'positron'}
    clubPrimaryColor={settingsQ.data?.primary_color}
    clubSecondaryColor={settingsQ.data?.accent_color}
    height={300}
  />
)}
```

### Coordinate Import Handler

```typescript
onImport={(coords: MapCoordinates) => {
  setLocationLat(coords.latitude);
  setLocationLng(coords.longitude);
  toast({
    title: 'Souřadnice importovány',
    description: `Lat: ${coords.latitude.toFixed(6)}, Lng: ${coords.longitude.toFixed(6)}`,
    status: 'success',
  });
}}
```
