Extend the built-in widgets

Sitefinity .NET Core Renderer comes with a set of built-in widgets, such as Navigation, Content list, and Content block. You can extend these widgets to suit your requirements in the following ways:

• Customize the views of the widgets
• Modify the logic behind the widgets
• Add fields to the widget designer

NOTE: The source code of the built-in widget is located in the .NET Core widgets GitHub repository.

You can add new or override the existing widget views.

You can do this by placing the file in the directory of your root web application using the following convention:
/Views/Shared/Components/{WIDGET_NAME}/{VIEW_NAME}.cshtml

Where:

• WIDGET_NAME is the name of the widget where the view will be added or overridden.
  For example, SitefinityContentBlock, SitefinityNavigation, or SitefinityContentList.
• VIEW_NAME is the name of the view you want to add or override.

You can modify the default or add custom logic to the behavior of a built-in widget by replacing a class in the .NET DI Container.

This is the Model class that all .NET Core widgets have – for example, IContentBlockModel, IContentListModel, or ISectionModel.
You can see all registered Model classes in the WidgetCollectionExtensions.cs class.

You can include additional fields in the widget designer.
You do this by extending the default Entity class that serves as the metadata source for the automatic generation of widgets.
