Angular Material 7 - Ripples

The <mat-ripple>, an Angular Directive, is used to define an area depicting the user interaction.

In this chapter, we will showcase the configuration required to draw a ripple effect using Angular Material.

Following is the content of the modified module descriptor app.module.ts.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {MatRippleModule, MatCheckboxModule, MatInputModule} from '@angular/material'
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
   declarations: [
   imports: [
      MatRippleModule, MatCheckboxModule, MatInputModule,
   providers: [],
   bootstrap: [AppComponent]
export class AppModule { }

Following is the content of the modified HTML host file app.component.html.

<mat-checkbox [(ngModel)] = "centered" class = "tp-ripple-checkbox">Centered</mat-checkbox>
<mat-checkbox [(ngModel)] = "disabled" class = "tp-ripple-checkbox">Disabled</mat-checkbox>
<mat-checkbox [(ngModel)] = "unbounded" class = "tp-ripple-checkbox">Unbounded</mat-checkbox>
   <mat-form-field class = "tp-ripple-form-field">
      <input matInput [(ngModel)] = "radius" type = "number" placeholder = "Radius">
   <mat-form-field class = "tp-ripple-form-field">
      <input matInput [(ngModel)] = "color" type = "text" placeholder = "Color">
<div class = "tp-ripple-container mat-elevation-z4"
   [matRippleCentered] = "centered"
   [matRippleDisabled] = "disabled"
   [matRippleUnbounded] = "unbounded"
   [matRippleRadius] = "radius"
   [matRippleColor] = "color">

Following is the content of the modified CSS file app.component.css.

.tp-ripple-container {
   cursor: pointer;
   text-align: center;
   width: 300px;
   height: 300px;
   line-height: 300px;
   user-select: none;
   -webkit-user-select: none;
   -moz-user-select: none;
   -ms-user-select: none;
   -webkit-user-drag: none;
   -webkit-tap-highlight-color: transparent;
.tp-ripple-checkbox {
   margin: 6px 12px 6px 0;
.tp-ripple-form-field {
   margin: 0 12px 0 0;

Following is the content of the modified ts file app.component.ts.

import { Component } from '@angular/core';
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
export class AppComponent {
   title = 'materialApp'; 
   centered = false;
   disabled = false;
   unbounded = false;
   radius: number;
   color: string;


Verify the result.



  • As first, we've created check boxes using mat-checkbox and bind them using ngModel with variables. These properties will be used to customize the ripple.

  • Then, we've created the ripple and showcased its various attributes bound with variables in .ts file.
