Adding a new html element using angular template

In Angular, you can add a new HTML element to a template using the following methods:

*Using the `ngFordirective**: You can use the*ngFor` directive to iterate over an array of objects and add a new HTML element for each item in the array.

Example:

<div *ngFor="let item of items">
  <p>{{ item.name }}</p>
  <button (click)="addItem()">Add new item</button>
</div>

In this example, the *ngFor directive is used to iterate over the items array and display each item's name. The addItem() function is called when the "Add new item" button is clicked, which adds a new item to the array.

Using the ng-container directive: You can use the ng-container directive to add a new HTML element that is not part of the component's template.

Example:

<ng-container *ngIf="showNewElement">
  <p>New element added!</p>
</ng-container>

In this example, the ng-container directive is used to add a new HTML element (New element added!) only when the showNewElement variable is true.

Using the innerHTML property: You can use the innerHTML property to add a new HTML element to a component's template.

Example:

import { Component } from '@angular/core';

@Component({
  selector: 'app-example',
  template: `
    <div [innerHTML]="newElement"></div>
  `
})
export class ExampleComponent {
  newElement = '<p>New element added!</p>';

  addItem() {
    this.newElement = '<p>New element added!</p>';
  }
}

In this example, the innerHTML property is used to add a new HTML element (New element added!) to the component's template. The addItem() function is called when the "Add new item" button is clicked, which updates the newElement property with a new HTML element.

Using the DOM property: You can use the DOM property to add a new HTML element to a component's template.

Example:

import { Component } from '@angular/core';

@Component({
  selector: 'app-example',
  template: `
    <div [dom]="newElement"></div>
  `
})
export class ExampleComponent {
  newElement: any;

  addItem() {
    this.newElement = document.createElement('p');
    this.newElement.textContent = 'New element added!';
  }
}

In this example, the DOM property is used to add a new HTML element (New element added!) to the component's template. The addItem() function is called when the "Add new item" button is clicked, which creates a new HTML element using the document.createElement() method and sets its text content to "New element added!".

Note that the DOM property is only available in Angular 12 and later versions. In earlier versions, you can use the innerHTML property instead.
