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 different available Fieldset Properties in Angular PrimeNG.

Fieldset Component is a grouping component that takes a header along with some content associated with that header having a toggle feature.
