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 Galleria Templates.
The Galleria Component is an advanced content gallery component. It is used for displaying images in an attractive manner. Galleria Templates can be used to customize it even more and add extra components to it such as header, caption, etc.
Angular PrimeNG Galleria Templates:
- header: It is the header component that is used to include the header in the template.
- indicator: It is the indicator component that will display the change in the Galleria Templates with the help of a solid small circle. It also helps to indicate the current active template with the solid small circle.
- caption: It is used to add a caption to an image.
- footer: It is the footer component that is used to include the content in the footer of the template.
Syntax: Add a template as follows
<p-galleria [numVisible]="3" [value]="images">
<ng-template pTemplate="item" let-item>
...
</ng-template>
<ng-template pTemplate="header" let-item>
...
</ng-template>
</p-galleria>
