+# Implementation Plan: Duration-Based Rental Filtering Based on Skipass Selection
+
+## Overview
+Implement cross-field dependency where rentals are only visible/selectable when a skipass is selected, and filter rentals to match the selected skipass's date range (dateFrom/dateTo).
+
+## Analysis
+Based on code review:
+- Both rentals and skipasses have `dateFrom` and `dateTo` properties for duration
+- Current system already filters services by travel date range using `getAdditionalServicesBySubTypes($token, true, true)`
+- Need to implement skipass-to-rental date matching logic
+- Field state conditions system is already in place for hiding/showing fields
+- Need to create a custom field options provider for duration-filtered rentals
+
+## Implementation Steps
+
+### 1. Create SkiPassSelectionCondition
+**File**: `src/Form/Service/Condition/SkiPassSelectionCondition.php`
+- Similar to `RentalSelectionCondition` but checks for skipass selection
+- Evaluates both form data and participant DTO for skipass
+- Returns true if participant has selected a skipass
+
+### 2. Update Field State Provider
+**File**: `src/Form/Service/CreateFieldStateProvider.php`
+- Add rentals field hidden condition based on skipass selection
+- Similar to how rental insurance is hidden unless rentals are selected:
+```php
+$skiPassCondition = new SkiPassSelectionCondition();
+$this->fieldStateConditions['rentals'] = [
+    'hidden' => CompositeCondition::not($skiPassCondition),
+];
+```
+
+### 3. Create Duration-Based Rental Filtering
+**File**: `src/Form/Service/ParticipantFieldOptionsProvider.php`
+- Modify existing rentals field provider to filter by selected skipass duration
+- Extract selected skipass from participant data
+- Filter available rentals to only those with matching dateFrom/dateTo ranges
+- Use exact date matching: `rental.dateFrom == skipass.dateFrom && rental.dateTo == skipass.dateTo`
+
+### 4. Update RentalsFieldHandler Dependencies
+**File**: `src/Form/Service/ParticipantRentalsFieldHandler.php`
+- Add `skiPass` to dependencies array: `['dateOfBirth', 'skiPass']`  
+- Add DTO cleanup: clear rentals when no skipass is selected
+- Filter rentals by skipass duration in `processField()` method
+
+### 5. Update Field Handler Dependencies
+**File**: `src/Form/Service/ParticipantRentalInsuranceFieldHandler.php`
+- Update dependencies to include skipass: `['dateOfBirth', 'rentals', 'skiPass']`
+- Modify visibility logic: rental insurance only shown when both skipass AND rentals selected
+
+## Key Technical Details
+
+### Duration Matching Logic
+Rentals will be filtered to match skipass duration exactly:
+```php
+private function filterRentalsBySkiPassDuration(array $rentals, ?Service $selectedSkiPass): array
+{
+    if (null === $selectedSkiPass || null === $selectedSkiPass->dateFrom || null === $selectedSkiPass->dateTo) {
+        return []; // No skipass or invalid dates = no rentals
+    }
+    
+    return array_filter($rentals, function(Service $rental) use ($selectedSkiPass) {
+        return $rental->dateFrom?->format('Y-m-d') === $selectedSkiPass->dateFrom?->format('Y-m-d') 
+            && $rental->dateTo?->format('Y-m-d') === $selectedSkiPass->dateTo?->format('Y-m-d');
+    });
+}
+```
+
+### Field Visibility Chain
+1. SkiPass: Always visible (after dateOfBirth)
+2. Rentals: Only visible when skipass selected, filtered by skipass duration
+3. Rental Insurance: Only visible when rentals selected (existing logic)
+4. Body Dimensions: Only visible when rentals selected (existing logic)
+
+### HTMX Integration
+- Existing HTMX system will handle dynamic updates when skipass selection changes
+- Field state conditions will automatically trigger rental field visibility
+- Rental options will be re-rendered with duration-filtered choices
+
+## Dependencies
+- No new dependencies required
+- Leverages existing field state condition system
+- Uses existing Service model date properties
+- Maintains backward compatibility with existing workflows
+
