Angular PrimeNG Slide Menu Popup

Last Updated : 19 Aug, 2022

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 how to use the SlideMenu Popup in Angular PrimeNG.

SlideMenu component is used to display the menu list in the form of the sliding animation which helps to see the menu items in a stepwise manner. By default, the SlideMenu is inline, but popup mode maybe is used by activating the popup property and invoking the toggle function with the event passed in from the anchor element.

Angular PrimeNG Slide Menu Popup Properties:

  • model: It is an array of menu items. It is of array data type & the default value is null.
  • popup: It defines if the menu would be displayed as a popup. It is of the boolean data type & the default value is false.
  • viewportHeight: It is the height of the scrollable area, a scrollbar appears if a menu height is longer than this value. It accepts the number data type as input & the default value is 175.

Syntax:

<button
    #btn
    type="button"
    pButton
    label="..."
    (click)="...">
</button>

<p-slideMenu #menu 
    [model]="gfg" 
    [popup]="true"
    [viewportHeight]="...">
</p-slideMenu>

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: After complete installation, it will look like the following:
