Items based on current URL

The breadcrumb items can be generated from the current URL of the page, if the url property is not provided or when the user does not specify the breadcrumb items using the BreadcrumbItemDirective tag. The following example shows the breadcrumb items that are generated based on the current URL.

This sample is hosted in different location, so the Breadcrumb Component is rendered with different location instead of the actual location.

Static URL

The breadcrumb items can be generated by providing the url property in the component, if the user does not specify the breadcrumb items using the BreadcrumbItemDirective tag. The following example shows the breadcrumb items generated from the provided url in the component.

Customize text when generated items using Url

The breadcrumb items text can be customized by using the beforeItemRender event. In the following example, bind-to-location text was customized as location.
