How can I create an advanced checkbox group using Angular Material?

You can create an advanced checkbox group in Angular Material by using the MatCheckbox component within a FormGroup. Would you like a code example?

Yes, please provide a code example.

Sure! Here’s a simple example:

import { Component } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';

@Component({
  selector: 'app-checkbox-group',
  template: `
    <form [formGroup]="form">
      <mat-checkbox formControlName="option1">Option 1</mat-checkbox>
      <mat-checkbox formControlName="option2">Option 2</mat-checkbox>
      <mat-checkbox formControlName="option3">Option 3</mat-checkbox>
    </form>
  `
})
export class CheckboxGroupComponent {
  form: FormGroup;

  constructor(private fb: FormBuilder) {
    this.form = this.fb.group({
      option1: [false],
      option2: [false],
      option3: [false]
    });
  }
}

How can I handle the checkbox state changes?

You can subscribe to the value changes of the FormGroup to handle state changes. Here’s how:

this.form.valueChanges.subscribe(values => {
  console.log('Checkbox states:', values);
});
