# Sprint 7: Visual Builder Theme Integration - COMPLETED ✅

**Date**: 2025-10-24
**Status**: ✅ Complete
**Overall Progress**: 80% → 85% (+5%)

---

## 🎯 Objectives

Integrate the theme system with the custom visual builder to allow users to:
1. Browse and use theme sections in the visual builder
2. Drag pre-designed theme components onto pages
3. Automatically inherit theme styles (colors, fonts)
4. Edit and customize theme sections within the builder
5. Save pages with theme component references

---

## ✅ What Was Accomplished

### 1. Controller Enhancement ✅
**Modified**: `app/Http/Controllers/PageController.php` (lines 364-397)

**Changes Made**:
- Updated `customBuilder()` method to load theme components
- Fetches active theme's section components
- Maps component data for builder consumption
- Passes `$themeComponents` to view

**Code Added**:
```php
// Load theme components for the website's active theme
$themeComponents = [];
if ($website->activeTheme) {
    $themeComponents = $website->activeTheme->components()
        ->whereHas('themeComponent', function ($q) {
            $q->where('type', 'section'); // Only load section components
        })
        ->with('themeComponent')
        ->get()
        ->map(function ($websiteComponent) {
            return [
                'id' => $websiteComponent->themeComponent->id,
                'name' => $websiteComponent->themeComponent->name,
                'slug' => $websiteComponent->themeComponent->slug,
                'description' => $websiteComponent->themeComponent->description,
                'type' => $websiteComponent->themeComponent->type,
                'builder_data' => $websiteComponent->customizations ?? $websiteComponent->themeComponent->builder_data,
                'variables' => $websiteComponent->themeComponent->variables,
            ];
        });
}
```

---

### 2. Theme Sections Palette ✅
**Modified**: `resources/views/pages/custom-builder.blade.php` (lines 117-139)

**UI Changes**:
- Added "THEME SECTIONS" category to component sidebar
- Displays all theme sections from active theme
- Each item shows name and description
- Draggable items with `data-theme-component-*` attributes

**Visual Layout**:
```
┌─────────────────────────────┐
│ COMPONENTS PANEL            │
├─────────────────────────────┤
│ BASIC                       │
│  ├─ Heading                 │
│  ├─ Paragraph               │
│  └─ Button                  │
├─────────────────────────────┤

│  │   Customer reviews       │
│  └─ 🔷 Contact Section      │
│      Contact form & info    │
└─────────────────────────────┘
```

### 3. Theme Style Inheritance ✅
**Modified**: `resources/views/pages/custom-builder.blade.php` (lines 13-77)

**CSS Variables Injection**:
- Injects theme colors as CSS variables (`--theme-primary`, `--theme-secondary`, etc.)
- Injects theme fonts as CSS variables (`--theme-font-heading`, `--theme-font-body`)
- Loads Google Fonts for theme typography
- Applies styles automatically to canvas elements

**Generated CSS**:
```css
:root {
    --theme-primary: #0066FF;
    --theme-secondary: #6c757d;
    --theme-dark: #1a1a1a;
    --theme-light: #f8f9fa;
    --theme-font-heading: 'Poppins', sans-serif;
    --theme-font-body: 'Inter', sans-serif;
}

.page-canvas h1, h2, h3, h4, h5, h6 {
    font-family: var(--theme-font-heading, inherit);
}

.page-canvas p, div, span, a {
    font-family: var(--theme-font-body, inherit);
}

.page-canvas .btn-primary {
    background-color: var(--theme-primary, #0066FF);
    border-color: var(--theme-primary, #0066FF);
}
```

**Benefits**:
- All builder components automatically use theme colors/fonts
- Consistent design across custom and theme components
- Real-time visual feedback of theme customization
- No manual styling required

---

### 4. Drag & Drop Integration ✅
**Modified**: `resources/views/pages/custom-builder.blade.php`

**Changes Made**:

#### A. Updated Drag Start Handler (lines 724-741)
```javascript
setupDragAndDrop() {
    document.querySelectorAll('.component-item').forEach(item => {
        item.addEventListener('dragstart', (e) => {
            e.dataTransfer.setData('text/plain', item.dataset.type);

            // If it's a theme section, also pass the component data
            if (item.dataset.type === 'theme-section') {
                e.dataTransfer.setData('theme-component-data', item.dataset.themeComponentData);
            }

            e.dataTransfer.effectAllowed = 'copy';
        });
    });
}
```

#### B. Updated Drop Handler (lines 750-774)
```javascript
element.addEventListener('drop', (e) => {
    e.preventDefault();
    e.stopImmediatePropagation();
    element.classList.remove('drag-over');

    const componentType = e.dataTransfer.getData('text/plain');
    if (componentType) {
        // Check if it's a theme section
        if (componentType === 'theme-section') {
            const themeDataStr = e.dataTransfer.getData('theme-component-data');
            if (themeDataStr) {
                try {
                    const themeComponentData = JSON.parse(themeDataStr);
                    this.addComponent(componentType, element, themeComponentData);
                } catch (error) {
                    console.error('Error parsing theme component data:', error);
                }
            }
        } else {
            this.addComponent(componentType, element);
        }
        e.dataTransfer.clearData();
    }
});
```

#### C. Enhanced addComponent Method (lines 777-793)
```javascript
addComponent(type, container, themeComponentData = null) {
    // Handle theme sections
    if (type === 'theme-section' && themeComponentData) {
        this.addThemeSection(themeComponentData, container);
        return;
    }

    // Handle smart column presets
    if (type.startsWith('columns-')) {
        this.addColumnPreset(type, container);
        return;
    }

    // ... existing code
}
```

        wrapper.className = 'component-wrapper theme-section-wrapper';
        wrapper.dataset.type = 'theme-section';
        wrapper.dataset.id = componentData.id;
        wrapper.dataset.themeComponentId = componentData.themeComponentId || '';
        wrapper.dataset.themeComponentSlug = componentData.themeComponentSlug || '';

        // Create a basic container to hold the theme section content
        const themeContent = document.createElement('div');
        themeContent.className = 'theme-section-content';
        wrapper.appendChild(themeContent);

        // Add component controls with badge
        const controls = document.createElement('div');
        controls.className = 'component-controls';
        controls.innerHTML = `
            <span class="badge bg-info me-2">Theme Section</span>
            <button class="btn btn-sm btn-outline-primary edit-btn">Edit</button>

    ->whereHas('themeComponent', function ($q) {
        $q->where('type', 'section');
    })
    ->with('themeComponent')
    ->get();
```

### 2. CSS Variables for Theme Styles

:root {
    --theme-primary: {{ $colors['primary']['default'] }};
    --theme-font-heading: '{{ $fonts['heading']['default'] }}';
}

.page-canvas .btn-primary {
    background-color: var(--theme-primary);
}
```

### 3. Recursive Component Rendering
```javascript
renderThemeComponent(builderData) {
    const container = document.createElement('div');

    if (builderData.type === 'container') {
        const containerEl = this.createContainerElement(builderData);
        container.appendChild(containerEl);

        // Recursively render children
        if (builderData.children && builderData.children.length > 0) {
            builderData.children.forEach(child => {
                const childEl = this.renderThemeComponent(child);
                const dropZone = containerEl.querySelector('.drop-zone') || containerEl;
                dropZone.appendChild(childEl);
            });
        }
    }

    return container.firstChild || container;
}
```

### 4. Data Persistence
```javascript
// Save theme component reference
if (type === 'theme-section') {
    component.themeComponentId = wrapper.dataset.themeComponentId;
    component.themeComponentSlug = wrapper.dataset.themeComponentSlug;
}

// Load theme component
if (componentData.type === 'theme-section') {
    wrapper.dataset.themeComponentId = componentData.themeComponentId;
    wrapper.dataset.themeComponentSlug = componentData.themeComponentSlug;
    // Restore children...
}
```
