Angular PrimeNG Accordion Selected
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 Selected in Angular PrimeNG, along with understanding the properties, along with their syntaxes that will be used in the code.
The Accordion component is used to display a section of custom content in tabs. The selected property that is set true, which allows either one-way binding or two-way binding, specifies the content’s visibility.
Syntax:
<p-accordion>
<p-accordionTab
header="..."
[selected]="true">
...
</p-accordionTab>
...
</p-accordion>
