Angular PrimeNG PanelMenu Animation Configuration

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. It provides a lot of templates, components, theme design, an extensive icon library, and much more. In this article, we will see the Angular PrimeNG PanelMenu Animation Configuration.

The PanelMenu component is in the form of a panel. It can be considered as a combination of accordion and tree components. The PanelMenu Animation Configuration allows us to configure the default animation when the component appears and then hides each section of the menu.

PanelMenu Animation Configuration properties:

• transitionOptions: Here we put the animation displayed when we open a panel of the menu. The default value is 400ms cubic-bezier(0.86, 0, 0.07, 1).

Syntax:

<p-panelMenu #menu 
    [model]="..." 
    [transitionOptions]="'...'">
</p-panelMenu>

        ];
    }
}

• app.module.ts:

Javascript

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";
import { PanelMenuModule } from "primeng/panelmenu";
import { AppComponent } from "./app.component";
import { ButtonModule } from "primeng/button";

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        PanelMenuModule,
        ButtonModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})

export class AppModule {}

Output

Example 2: In the following example, we have disabled the animation using transitionOptions.
