Appearance in Angular Rating Component

26 Feb 202617 minutes to read

You can also customize the appearance of rating component.

Items count

You can specify the number of rating items using the itemsCount property.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" itemsCount="8" value="3"/>
                </div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Disabled

You can disable the rating component by using the disabled property. When the disabled property is set to true, the rating component will be disabled and the user will not be able to interact with it and a disabled rating component may have a different visual appearance than an enabled one.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" value="3" disabled="true" />
                </div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Visible

can use the visible property of the rating component to control the visibility of the component. When the visible property is set to true, the rating component is displayed on the page. When it is set to false, the component is hidden.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

import { Component, ViewChild } from '@angular/core';
import { RatingComponent } from '@syncfusion/ej2-angular-inputs';

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <button id="btn" (click)="visible()">Visible</button>
                    <input ejs-rating #rating id="rating" value="3" visible="true" />
                </div>`
})

export class AppComponent {

  @ViewChild('rating')
  public rating?: RatingComponent;

  public visible() {
    this.rating!.visible = !this.rating?.visible;
  }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Read only

Use the readOnly property to render the rating component in a non-interactive state, preventing users from modifying the rating value.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" value="3" readOnly="true" />
                </div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

CSS classes

Customize the rating component’s appearance—including colors, fonts, sizes, and other visual aspects—using the cssClass property. The following sections demonstrate common customization techniques.

Changing rating symbol border color

Modify the rating icon border color by applying the cssClass property and setting the text-stroke CSS property of .e-rating-icon to your desired color.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" value="3" cssClass="custom-border" />
                </div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

index.css

/* Represents the styles for loader */
#loader {
  color: #008cff;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}

.wrap {
  margin: 50px auto;
  text-align: center;
}

.e-rating-container.custom-border .e-rating-item-list:hover .e-rating-item-container .e-rating-icon,
.e-rating-container.custom-border .e-rating-item-container .e-rating-icon {
    /* To change rating symbol border color */
    -webkit-text-stroke: 2px #ae9e9d;
}

Changing rated/un-rated symbol fill color

Customize the fill colors of rated and unrated icons by using the cssClass property and applying linear-gradient color-stops in the background CSS property of .e-rating-icon. The first color-stop defines the rated fill color and the second color-stop defines the unrated fill color.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" value="3" cssClass="custom-fill" />
                </div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

index.css

/* Represents the styles for loader */
#loader {
  color: #008cff;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}

.wrap {
  margin: 50px auto;
  text-align: center;
}

.e-rating-container.custom-fill .e-rating-item-list:hover .e-rating-item-container .e-rating-icon,
.e-rating-container.custom-fill .e-rating-item-container .e-rating-icon {
    /* To change rated symbol fill color and un-rated symbol fill color */
    background: linear-gradient(to right, #ffe814 var(--rating-value), #d8d7d4 var(--rating-value));
    background-clip: text;
    -webkit-background-clip: text;
}

This customizes the rated fill color to #ffe814 and unrated fill color to #d8d7d4. The --rating-value variable in the linear-gradient represents the current rating value.

Changing the item spacing

Adjust the space between rating items by using the cssClass property and setting the margin or padding CSS properties of .e-rating-item-container to your desired value.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" value="3" cssClass="custom-font" />
                </div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

index.css

/* Represents the styles for loader */
#loader {
  color: #008cff;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}

.wrap {
  margin: 50px auto;
  text-align: center;
}

.e-rating-container.custom-font .e-rating-item-container {
  /* To change the size between items */
  margin: 0px 7px;
}

Changing icon using CSS classes

Replace the default rating item icon by using the cssClass property and setting the content CSS property of .e-icons.e-star-filled:before to your desired font icon character code.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { RatingModule } from '@syncfusion/ej2-angular-inputs'
import { enableRipple } from '@syncfusion/ej2-base'

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

@Component({
imports: [
         FormsModule, RatingModule
    ],


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render Rating component. -->
                <div class="wrap">
                    <input ejs-rating id="rating" value="3" cssClass="custom-icon" />
                </div>`
})
