Angular PrimeNG Accordion Styling

Last Updated : 28 Apr, 2025

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will see the Angular PrimeNG Accordion Styling.

An Accordion Component is used to display a section of custom content in tabs.

Angular PrimeNG Accordion Styling:

p-accordion: it is the container element.
p-accordion-header: it is the header of a tab.
p-accordion-content: it is the content of a tab.

Syntax

<p-accordion>
    <p-accordionTab header="Header">
        Content 
    </p-accordionTab>
 </p-accordion>

Creating Angular application & module installation:

Step 1: Create an Angular application using the following command.

ng new appname

Step 2: After creating your project folder i.e. appname, move to it using the following command.

cd appname

Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: It will look like the following:

Example 1: This example illustrates the use of the Angular PrimeNG Accordion Styling, where the first accordion is initially selected. Here, we have implemented the p-accordion and p-accordion-content.

JavaScript

import { NgModule } from "@angular/core";
import { BrowserModule } 
    from "@angular/platform-browser";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";
