Angular PrimeNG Splitter Nested Panels - Coding

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 know how to use the Splitter Nested Panels in Angular PrimeNG. We will also learn about the properties, events & styling along with their syntaxes that will be used in the code.

Splitter Component allows a user to split two-element using a splitter & utilized it separately and resize panels. The Nested Splitter Panels can be used to combine more than 2 panels, in order to create an advanced layout structure.

Angular PrimeNG Splitter Nested Panels properties:

panelSizes: It is used to specify the initial size of the panel. It is of number data type & the default value is null.
layout: It is used to set the orientation of the panels. It is of string data type & the default value is horizontal.
style: It is used to specify the inline style of the component. It is of object data type & the default value is null.
minSizes: It is used to specify the minimum size of the elements. It is of number data type & the default value is null.

Syntax:

<p-splitter [style]="..." [panelSizes]="...">
   <ng-template pTemplate>
      ...
   </ng-template>
        
   <ng-template pTemplate>
      <p-splitter layout="..." [panelSizes]="...">
          <ng-template pTemplate>
              ...
          </ng-template>
                
          <ng-template pTemplate>
              ...
          </ng-template>
      </p-splitter>
   </ng-template>
  </p-splitter>
</div>

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 is the basic example that illustrates how to use the Angular PrimeNG Splitter Nested Panels.

app.component.html

<div style="text-align: center"> 
  <h2 style="color:green">GeeksforGeeks</h2> 
  <h5>PrimeNG Splitter Nested Panels</h5> 
</div> 
<p-splitter
    [style]="{ height: '250px' }" 
    [panelSizes]="[20, 80]" 
    [minSizes]="[10, 50]" 
    styleClass="mb-5"> 
    <ng-template pTemplate> 
      <div class="col flex align-items-center

app.component.ts

import { Component } from "@angular/core"; 
  
@Component({ 
  selector: "my-app",

Example 2: This is another example that illustrates how to use the Angular PrimeNG Splitter Nested Panels with some different [panelSizes] and content as an image.

app.component.html

  <h5>PrimeNG Splitter Nested Panels</h5>
