Angular 16: guide with NgFor and Dynamic Component Rendering within a FormGroup
I'm working with a scenario with rendering dynamic components inside an Angular reactive form using `ngFor`. I have a `FormGroup` that contains a `FormArray`, and each item in this `FormArray` should render a specific component based on a type property. However, when I try to dynamically render these components based on their type, I'm running into an behavior that states 'No provider for ComponentType'. I'm using Angular 16 and have tried several approaches to inject the component dynamically, but I keep hitting this wall. Here's a simplified version of what I have: ```typescript import { Component, Input, ViewChild, ViewContainerRef, ComponentFactoryResolver } from '@angular/core'; import { FormBuilder, FormGroup, FormArray } from '@angular/forms'; @Component({ selector: 'app-dynamic-form', template: ` <form [formGroup]="formGroup"> <div formArrayName="items"> <ng-container *ngFor="let item of items.controls; let i = index"> <ng-container *ngIf="item.type === 'text'"> <app-text-input [formControl]="item.control"></app-text-input> </ng-container> <ng-container *ngIf="item.type === 'select'"> <app-select-input [formControl]="item.control"></app-select-input> </ng-container> </ng-container> </div> </form> `, }) export class DynamicFormComponent { formGroup: FormGroup; constructor(private fb: FormBuilder) { this.formGroup = this.fb.group({ items: this.fb.array([]), }); } get items() { return this.formGroup.get('items') as FormArray; } addItem(type: string) { this.items.push(this.fb.control('', [])); this.items.at(this.items.length - 1).type = type; // trying to set type dynamically } } ``` When I try to render the `app-text-input` or `app-select-input` components, I get the following behavior message in the console: ``` behavior behavior: Uncaught (in promise): NullInjectorError: No provider for ComponentType! ``` I've verified that both components are declared in the same module and imported correctly. I've also checked that the dynamic components are included in an `entryComponents` array, but it doesn't seem to help. What am I doing wrong? Is there a better way to handle dynamic form components in Angular 16? Any guidance would be appreciated!
