-Title: Form Extensibility for APA Form Widget
-Added: v4.1.0

-## Form Extensibility for APA Form Widget
-This page describes how you can customize ADF forms to your own specification.
-
-## Contents
-There are two ways to customize the form
--   [Replace default form widgets with custom components](#replace-default-form-widgets-with-apa-form-widgets)
--   [Replace custom form widget with custom components](#replace-custom-form-widgets-with-custom-components)
-
-## Replace default form widgets with APA form widgets
-
-This is an example of replacing the standard `Text` [widget](../../lib/testing/src/lib/core/pages/form/widgets/widget.ts) with a custom component for all APA forms rendered within the `<adf-form>` component.
-
-1. Create a simple form with some `Text` widgets:
-
-    ![default text widget](../docassets/images/apa-simple-form.png)
-
-    Every custom widget component must inherit the [`WidgetComponent`](../insights/components/widget.component.md) class in order to function properly:
-
-    ```ts
-    import { Component } from '@angular/core';
-    import { WidgetComponent } from '@alfresco/adf-core';
-    @Component({
-        selector: 'custom-editor',
-        template: `
-            <div style="color: red">Look, I'm a APA custom editor!</div>
-        `
-    })
-    export class CustomEditorComponent extends WidgetComponent {}
-    ```
-
-2. Add it to the application module or any custom module that is imported into the application one:
-
-    ```ts
-    import { NgModule } from '@angular/core';
-    import { CustomEditorComponent } from './custom-editor.component';
-    @NgModule({
-        declarations: [ CustomEditorComponent ],
-        exports: [ CustomEditorComponent ]
-    })
-    export class CustomEditorsModule {}
-    ```
-
-3. Every custom widget component should be added into the the collections `declarations` and `exports`. If you decided to store custom widgets in a separate dedicated module (and optionally as a separate re-distributable library) don't forget to import it into the main application:
-
-    ```ts
-    @NgModule({
-        imports: [
-            // ...
-            CustomEditorsModule
-            // ...
-        ],
-        providers: [],
-        bootstrap: [ AppComponent ]
-    })
-    export class AppModule {}
-    ```
-
-4. Import the [`FormRenderingService`](../core/services/form-rendering.service.md) into any of your Views and override the default mapping, for example:
-
-    ```ts
-    import { Component } from '@angular/core';
-    import { CustomEditorComponent } from './custom-editor.component';
-    @Component({...})
-    export class MyView {
-        constructor(formRenderingService: FormRenderingService) {
-            this.formRenderingService.register({
-                'text': () => CustomEditorComponent
-            }, true);
-        }
-    }
-    ```
-
-5. At runtime the form should look similar to the following:
-
-    ![custom text widget](../docassets/images/apa-simple-override-form.png)
-
-
-## Replace custom form widgets with custom components
-
-This is an example of rendering custom form widgets using custom Angular components.
-
-### Create a custom form widget
-
-To begin, create a basic form widget and call it `demo-widget`:
-
-![custom form widget](../docassets/images/apa-form-widget.png)
-
-**Note**: The `type` is important as it will become the `field type` when the form is rendered.
-
-You can now design a form that uses your custom form widget:
-
-![custom form widget form](../docassets/images/apa-form-with-widget.png)
-
-### Create a custom widget
-
-When displayed in a task, the field will look similar to the following:
-
-![adf form widget](../docassets/images/apa-unresolved-widget.png)
-
-
-To render the missing content:
-
-1. Create an Angular component:
-
-    ```ts
-    import { Component } from '@angular/core';
-    import { WidgetComponent } from '@alfresco/adf-core';
-    @Component({
-        selector: 'app-demo-widget',
-        template: `<div style="color: green">ADF version of custom form widget</div>`
-    })
-    export class DemoWidgetComponent extends WidgetComponent {}
-    ```
-
-2. Place it inside the custom module:
-
-    ```ts
-    import { NgModule } from '@angular/core';
-    import { DemoWidgetComponent } from './demo-widget.component';
-    @NgModule({
-        declarations: [ DemoWidgetComponent ],
-        exports: [ DemoWidgetComponent ]
-    })
-    export class CustomWidgetsModule {}
-    ```
-
-3. Import it into your Application Module:
-
-    ```ts
-    @NgModule({
-        imports: [
-            // ...
-            CustomWidgetsModule
-            // ...
-        ],
-        providers: [],
-        bootstrap: [ AppComponent ]
-    })
-    export class AppModule {}
-    ```
-
-4. Import the [`FormRenderingService`](../core/services/form-rendering.service.md) in any of your Views and provide the new mapping:
-
-    ```ts
-    import { Component } from '@angular/core';
-    import { DemoWidgetComponent } from './demo-widget.component';
-    @Component({...})
-    export class MyView {
-        constructor(formRenderingService: FormRenderingService) {
-            this.formRenderingService.register({
-                'custom-editor': () => DemoWidgetComponent
-            });
-        }
-    }
-    ```
-
-At runtime you should now see your custom Angular component rendered in place of the original form widgets:
