13 Jun 202417 minutes to read

you can adjust the size of the TextArea by applying specific classes:

Property	Description
Small	Add the e-small class to the input element or its container to render a smaller-sized TextArea.
Bigger	Add the e-bigger class to the input element or its container to render a larger-sized TextArea.

By applying these classes, users can easily customize the appearance of the TextArea to better fit their application’s design requirements.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import {TextAreaModule} from '@syncfusion/ej2-angular-inputs'



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

@Component({
imports: [
        
        TextAreaModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="wrap">
                <div class='textarea'>
                  <h4> Small Size </h4>
                  <div className="e-input-group e-small">
                      <ejs-textarea id="default1" className="e-input" placeholder="Enter your comments" (focus)= "onfocus($event)" (blur)="onBlur($event)"></ejs-textarea>
                  </div>

                  <h4> Bigger Size </h4>
                  <div className="e-input-group e-bigger">
                      <ejs-textarea id="default2" className="e-input" placeholder="Enter your comments" (focus)= "onfocus($event)" (blur)="onBlur($event)"></ejs-textarea>
                  </div>
                </div>
              </div>`
})

export class AppComponent {
    public onfocus(args: any): void {
      args.target.parentElement.classList.add("e-input-focus");
    }

    public onBlur(args: any): void {
      args.target.parentElement.classList.remove("e-input-focus");
    }
 }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';

Filled and outline mode

The Filled and Outline modes can be enabled in the TextArea component by adding the e-outline or e-filled class to the cssClass API.
By adding these classes, users can choose between a filled or outline appearance for the TextArea component, aligning with the design aesthetics of their application.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import {TextAreaModule} from '@syncfusion/ej2-angular-inputs'



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

@Component({
imports: [
        
        TextAreaModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="wrap">
                <div class='textarea'>
                <label className="custom-input-label"> Filled TextArea </label>
                <div id='container'>
                    <ejs-textarea id='filled' placeholder="Filled" floatLabelType="Auto" cssClass="e-filled"></ejs-textarea>
                </div>
            
                <label className="custom-input-label"> Outlined TextArea </label>
                <div id='container1'>
                    <ejs-textarea id='outlined' placeholder="Outlined" floatLabelType="Auto" cssClass="e-outline"></ejs-textarea>
                </div>
                </div>
              </div>`
})

export class AppComponent { }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
