Angular Bootstrap checkbox

Angular Checkbox - Bootstrap 4 & Material Design

Note: This documentation is for an older version of Bootstrap (v.4). A newer version is available for Bootstrap 5. We recommend migrating to the latest version of our product - Material Design for Bootstrap 5.
Go to docs v.5

Angular Bootstrap checkbox is a component used to allow a user to make a multiple choice. It is broadly used in the forms and surveys.

Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.

Default checkboxes

Default styling for Angular Bootstrap Checkbox component



                <!-- Default unchecked -->
                <mdb-checkbox [default]="true">Default unchecked</mdb-checkbox>

Material checkboxes MDB Pro component

Material Design styling for Angular Bootstrap Checkbox component



                <!-- Material unchecked -->
                <mdb-checkbox>Material unchecked</mdb-checkbox>

Checked state

Add a [checked]="true" input to the pre-select checkbox when the page loads.

Default checkbox 



              <!-- Default checked -->
              <mdb-checkbox [checked]="true" [default]="true">Default checked</mdb-checkbox>

Material checkbox MDB Pro component 



              <!-- Material checked -->
              <mdb-checkbox [checked]="true">Material checked</mdb-checkbox>

Indeterminate state

Note: The indeterminate state is visual only. The checkbox is still either checked or unchecked as a state.

Add an [indeterminate]="true" input to set an indeterminate state to your checkbox

Default checkbox 



              <!-- Default indeterminate -->
              <mdb-checkbox [indeterminate]="true" [default]="true">Default checked</mdb-checkbox>

Material checkbox MDB Pro component 



                <!-- Material indeterminate -->
                <mdb-checkbox [indeterminate]="true">Material checked</mdb-checkbox>

Disabled state

Add an [disabled]="true" input and the custom indicator and label description will be automatically styled and blocked.

A disabled checkbox component is unusable and un-clickable.

Default checkbox 



              <!-- Default unchecked disabled -->
              <mdb-checkbox [disabled]="true" [default]="true">Default unchecked disabled</mdb-checkbox>

              <mdb-checkbox [disabled]="true" [checked]="true" [default]="true">Default checked disabled</mdb-checkbox>

Material checkbox MDB Pro component 



              <!-- Material unchecked disabled -->

              <!-- Material checked disabled -->
              <mdb-checkbox [disabled]="true" [checked]="true">Material checked disabled</mdb-checkbox>

Inline

Add an [inline]="true" input to group checkboxes on the same horizontal row.

Default checkboxes 



              <!-- Default inline 1-->
              <mdb-checkbox [inline]="true" [default]="true">1</mdb-checkbox>

              <mdb-checkbox [inline]="true" [default]="true">2</mdb-checkbox>

              <mdb-checkbox [inline]="true" [default]="true">3</mdb-checkbox>

Material checkboxes MDB Pro component 



              <!-- Material inline 1 -->
              <mdb-checkbox [inline]="true">1</mdb-checkbox>

Template-driven forms MDB Pro component

In this section, you will find information on how to use our checkbox component in template-driven forms.

Remember to import FormsModule into your app.module.ts file.

Setting & getting the value

Just bind in a two-way ngModel from component.html with templateChecked or templateUnchecked in the component.ts file


        <form>
          <mdb-checkbox [(ngModel)]="templateChecked" name="templateChecked">Checked with ngModel</mdb-checkbox>
          <mdb-checkbox [(ngModel)]="templateUnchecked" name="templateUnchecked">Unchecked with ngModel</mdb-checkbox>
        </form>
        <button mdbBtn color="primary" mdbWavesEffect (click)="getCheckboxesValue()">Get checkboxes value</button>
      

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

        @Component({
          selector: 'template-driven-checkbox',
          templateUrl: 'template-driven-checkbox.component.html',
        })

        export class TemplateDrivenCheckboxComponent {
          templateChecked = true;
          templateUnchecked = false;

          getCheckboxesValue() {
            console.log('Checked value:', this.templateChecked);
            console.log('Unchecked value:', this.templateUnchecked);
          }
        }

Reactive forms MDB Pro component

In this section, you will find information on how to use our checkbox component in reactive forms.

Remember to import ReactiveFormsModule into your app.module.ts file.

Setting & getting the value

Set the default value in FormControl


        <form [formGroup]="reactiveForm">
          <mdb-checkbox formControlName="checked">Checked with FormControl</mdb-checkbox>
          <mdb-checkbox formControlName="unchecked">Unchecked with FormControl</mdb-checkbox>
        </form>
        <button mdbBtn color="primary" mdbWavesEffect (click)="getCheckboxesValue()">Get checkboxes value</button>
      

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

        @Component({
        selector: 'reactive-forms-checkbox',
        templateUrl: 'reactive-forms-checkbox.component.html',
        })

        export class ReactiveFormsCheckboxComponent {
          reactiveForm: FormGroup = new FormGroup({
            checked: new FormControl(true),
            unchecked: new FormControl(false)
          });

          getCheckboxesValue() {
            console.log('Checked value:', this.reactiveForm.controls['checked'].value);
            console.log('Unchecked value:', this.reactiveForm.controls['unchecked'].value);
          }
        }

import { CheckboxModule, WavesModule, ButtonsModule } from 'ng-uikit-pro-standard'
// MDB Angular Free
import { CheckboxModule, WavesModule, ButtonsModule } from 'angular-bootstrap-md'
