Angular PrimeNG Accordion Multiple

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 Accordion Multiple in Angular PrimeNG, along with understanding the properties, & their syntaxes that will be used in the code.

The Accordion component is used to display a section of custom content in tabs. By default, only a single tab is allowed to be active at a time. Enabling the multiple=true attribute alters the normal behavior of the browser, where the multiple tabs are allowed to be active at the same time.

Syntax:

<p-accordion [multiple]="true">
    <p-accordionTab header="...">
           .....
    </p-accordionTab>
    .......
</p-accordion>
