+# Angular + Formeo Integration Guide
+
+## Why the Demo Doesn't Load Real Angular v20
+
+The current Angular demo in `src/demo/js/frameworks/angular.js` simulates Angular patterns rather than loading the actual Angular framework for several technical reasons:
+
+### Technical Limitations
+
+1. **Dynamic ES Module Loading Complexity**
+   - Angular v20 requires complex module resolution
+   - Dependencies between @angular/core, @angular/common, @angular/platform-browser
+   - Browser ES module loading limitations
+
+2. **Bundle Size Impact**
+   - Angular v20 with dependencies is ~200KB+ minified
+   - Would significantly slow down demo loading
+   - Not suitable for quick demonstrations
+
+3. **Build Tool Requirements**
+   - Angular typically requires compilation (TypeScript → JavaScript)
+   - Template compilation and bundling
+   - Zone.js and other runtime dependencies
+
+4. **Runtime Environment Mismatch**
+   - Demo runs in vanilla browser environment
+   - Angular expects Node.js tooling ecosystem
+
+## Recommended Alternatives
+
+### Option 1: Complete Angular Project Example (Recommended)
+
+Create a separate Angular project that demonstrates real integration:
+
+```bash
+# Create new Angular project
+ng new formeo-angular-example --routing --style=scss
+cd formeo-angular-example
+
+# Install Formeo
+npm install formeo
+
+# Run development server
+ng serve
+```
+
+**Benefits:**
+- Real Angular v20 environment
+- Proper TypeScript support
+- Full Angular CLI tooling
+- Production-ready patterns
+
+### Option 2: Improved CDN Loading (Experimental)
+
+Update the demo to use Angular's standalone CDN bundles:
+
+```javascript
+// Load Angular via CDN (Angular v20 standalone)
+async function loadAngularFromCDN() {
+  const scripts = [
+    'https://unpkg.com/@angular/core@20/bundles/core.umd.js',
+    'https://unpkg.com/@angular/common@20/bundles/common.umd.js',
+    'https://unpkg.com/@angular/platform-browser@20/bundles/platform-browser.umd.js'
+  ];
+
+  for (const src of scripts) {
+    await loadScript(src);
+  }
+}
+```
+
+**Limitations:**
+- Still complex dependency management
+- Large download size
+- Limited TypeScript support
+- Not recommended for production
+
+### Option 3: Web Components Approach
+
+Use Angular Elements to create a web component:
+
+```typescript
+// Create Angular Element
+import { createCustomElement } from '@angular/elements';
+import { FormBuilderComponent } from './form-builder.component';
+
+const FormBuilderElement = createCustomElement(FormBuilderComponent, { injector });
+customElements.define('formeo-angular-builder', FormBuilderElement);
+```
+
+**Benefits:**
+- Can be loaded in any environment
+- Encapsulated Angular functionality
+- Framework-agnostic usage
+
+### Option 4: Stackblitz/CodeSandbox Integration
+
+Embed live Angular examples using online IDEs:
+
+```html
+<iframe src="https://stackblitz.com/edit/formeo-angular-v20?embed=1"
+        width="100%" height="600px"></iframe>
+```
+
+## Current Demo Value
+
+The current simulated demo is still valuable because it:
+
+1. **Shows Integration Patterns**: Demonstrates proper Angular component structure
+2. **Provides Copy-Paste Code**: Complete, working examples for real projects
+3. **Educational Value**: Teaches Angular + Formeo integration concepts
+4. **Performance**: Loads quickly without framework overhead
+
+## Implementation Recommendation
+
+For your use case, I recommend:
+
+1. **Keep the current demo** for quick pattern demonstration
+2. **Add a complete Angular project** in `/docs/angular-integration-example/`
+3. **Update the demo documentation** to clearly explain the simulation
+4. **Add links to the full project** for developers who want real integration
+
+This approach provides both quick learning (demo) and complete implementation (separate project).
+
+## Migration Path
+
+If you want to enhance the current demo:
+
+```javascript
+// Enhanced demo with better Angular simulation
+export async function loadAngularDemo(container) {
+  // 1. Show comprehensive setup instructions
+  // 2. Provide modern Angular v20 code examples
+  // 3. Demonstrate advanced patterns (signals, standalone components)
+  // 4. Include service-based architecture examples
+  // 5. Add TypeScript type definitions
+}
+```
+
+The updated demo now includes:
+- Modern Angular v20 patterns
+- Standalone components
+- Angular signals
+- Service-based architecture
+- Better TypeScript examples
+- Comprehensive integration guide

+# FormeoEditor.clear() Method
+
+## Overview
+
+The `clear()` method has been added to the FormeoEditor class to provide a clean way to reset the editor to its initial state, as if no form data was ever provided.
+
+## Method Signature
+
+```typescript
+editor.clear(): void
+```
+
+## Description
+
+The `clear()` method:
+- Resets the internal `userFormData` to the default form structure using `DEFAULT_FORMDATA()`
+- Maintains the proper form structure with at least one empty stage
+- Reloads the Components with the default form data
+- Re-renders the editor to show the clean, initial state
+- Effectively returns the editor to its initial state while preserving the required stage structure
+
+## Usage Examples
+
+### Basic Usage
+```javascript
+import { FormeoEditor } from 'formeo';
+
+const editor = new FormeoEditor({
+  editorContainer: '#my-editor'
+});
+
+// ... user builds a form ...
+
+// Clear the form back to empty state
+editor.clear();
+```
+
+### React Hook Example
+```javascript
+const clearForm = useCallback(() => {
+  if (editorRef.current) {
+    editorRef.current.clear();
+    setFormData(null);
+  }
+}, []);
+```
+
+### Angular Component Example
+```typescript
+clearForm() {
+  if (this.editor) {
+    this.editor.clear();
+  }
+  if (this.renderer && this.renderContainer) {
+    this.renderContainer.nativeElement.innerHTML = '';
+  }
+}
+```
+
+## When to Use
+
+Use the `clear()` method when you need to:
+- Reset the form builder to a blank state
+- Start over with a new form
+- Clear all form stages and fields
+- Return to the initial editor state
+
+## Comparison with formData Setter
+
+| Method | Purpose | Result |
+|--------|---------|---------|
+| `editor.clear()` | Reset to initial state with proper structure | Clean editor with one empty stage |
+| `editor.formData = {}` | Set specific form data | May break editor structure |
+
+The `clear()` method is more reliable as it uses the proper default form structure and maintains at least one stage.
+
+## Integration with Framework Demos
+
+Both React and Angular demos now use the `clear()` method:
+- **Interactive Demo**: Clear button uses `editor.clear()`
+- **Code Examples**: All framework patterns updated to use the new method
+- **Error-Free**: No more "clear is not a function" errors
+
+## Benefits
+
+1. **Official API**: Now part of the FormeoEditor public API
+2. **Consistent**: Same behavior across all framework integrations
+3. **Complete Reset**: Thoroughly clears all editor state
+4. **Future-Proof**: Will work with future Formeo updates
