## 💡 Technical Details
|
||||
|
||||
### Live Preview System
|
||||
|
||||
**How it works**:
|
||||
```typescript
|
||||
// 1. User makes change in editor
|
||||
handleVariantChange(elementName, variant)
|
||||
|
||||
// 2. Editor dispatches custom event
|
||||
window.dispatchEvent(new CustomEvent('elementor-change', {
|
||||
detail: { elementName, variant, visible }
|
||||
}))
|
||||
|
||||
// 3. Hook listens and updates state
|
||||
useEffect(() => {
|
||||
window.addEventListener('elementor-change', handleChange)
|
||||
}, [])
|
||||
|
||||
// 4. Component re-renders with new variant/visibility
|
||||
<ConditionalElement visible={isVisible('gallery')}>
|
||||
<GallerySection variant={getVariant('gallery')} />
|
||||
</ConditionalElement>
|
||||
```
|
||||
|
||||
### Database Schema
|
||||
|
||||
**Updated fields**:
|
||||
```sql
|
||||
CREATE TABLE page_element_configs (
|
||||
...
|
||||
variant VARCHAR NOT NULL,
|
||||
visible BOOLEAN DEFAULT true, -- NEW
|
||||
display_order INTEGER DEFAULT 0 -- NEW
|
||||
)
|
||||
```
|
||||
|
||||
### Save Without Reload
|
||||
|
||||
**New behavior**:
|
||||
```typescript
|
||||
// OLD: Page reload after save
|
||||
window.location.reload()
|
||||
|
||||
// NEW: Just save to database
|
||||
await batchUpdatePageElementConfigs(configs)
|
||||
toast({ title: 'Saved without reload!' })
|
||||
```
|
||||

import { useAllPageElementConfigs } from '../hooks/usePageElementConfig';
|
||||
import ConditionalElement from '../components/editor/ConditionalElement';
|
||||
import ElementorStyleEditor from '../components/editor/ElementorStyleEditor';
|
||||
|
||||
const HomePage = () => {
|
||||
const { getVariant, isVisible } = useAllPageElementConfigs('homepage');
|
||||
|
||||
return (
|
||||
<MainLayout>
|
||||
<ElementorStyleEditor pageType="homepage" />
|
||||
|
||||
{/* Header - always visible */}
|
||||
<EditableElement elementName="header">
|
||||
<HeaderVariants variant={getVariant('header')} />
|
||||
</EditableElement>
|
||||
|
||||
{/* Gallery - conditionally visible */}
|
||||
<ConditionalElement visible={isVisible('gallery', false)}>

<VideosSection variant={getVariant('videos')} />
|
||||
</EditableElement>
|
||||
</ConditionalElement>
