Styling Modes in Angular OTP Input component

26 Feb 20266 minutes to read

Styling modes define the visual presentation of the OTP input fields. Choose a styling mode based on your design requirements and user experience goals. Three predefined modes are available: outlined (default), filled, and underlined.

Outlined mode

The outlined style displays input fields with a visible border and background. This is the default styling mode and provides clear visual boundaries for each OTP field. Set the stylingMode property to outlined to apply this style.

app.component.ts

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

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

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


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render OTP Input component. -->
    <div class="wrap">
        <div id='otp-container' style="width: 350px;">
            <div ejs-otpinput stylingMode="outlined"></div>
        </div>
    </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;
}

Filled mode

The filled style displays input fields with a solid background color and no border, creating a modern, compact appearance. Use this mode for designs that emphasize background-based separation. Set the stylingMode property to filled to apply this style.

app.component.ts

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

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

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


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render OTP Input component. -->
    <div class="wrap">
        <div id='otp-container' style="width: 350px;">
            <div ejs-otpinput stylingMode="filled"></div>
        </div>
    </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;
}

Underlined mode

The underlined style displays input fields with only a bottom border, creating a minimalist appearance. This mode is useful for space-constrained interfaces or mobile applications. Set the stylingMode property to underlined to apply this style.

app.component.ts

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

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

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


standalone: true,
  selector: 'app-root',
  template: `<!-- To Render OTP Input component. -->
    <div class="wrap">
        <div id='otp-container' style="width: 350px;">
            <div ejs-otpinput stylingMode="underlined"></div>
        </div>
    </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;
}
