hrefattribute of the Breadcrumb items.
The ASP.NET Core Breadcrumb is one of the many components in the suite with out-of-the-box support for keyboard navigation. Users can use the arrows to open or close a node on focus or to navigate to other items in the chart.
The ASP.NET Core Breadcrumb has several built-in themes and swatches. Explore the Default (our own styling), Material (based on the Material Design guidelines), Bootstrap (which looks like the Bootstrap styling to integrate better) and Fluent (based on Microsoft Fluent UI) themes and choose the swatch that meets your design requirements. You can easily customize any theme with a few lines of CSS or create a new one with the Progress SASS ThemeBuilder application to exactly match your colors and branding.
