Classification widget


You use the ASP.NET Core Classification built-in widget to display lists of categories, tags, or custom classifications on your website. You then use these lists of classifications to filter the content of the pages.

EXAMPLE: If you have a list of news, some of which are news about the weather and you have tagged them with the tag weather, and some news are about the traffic and you have tagged them with tag traffic, by adding the Tags widget to your page, you give the users the opportunity to filter only traffic or only weather news by clicking the respective tag.

Classifications are created and managed in the Classifications module. You use the widget only to display them.
For more information, see Classify content.
