# KB Knowledge Bases widget

Give users the option to select which knowledge base to browse on your portal. You can use this base system widget as-is in your portal or clone it to suit your own business needs.

## Using the widget

If you associate your portal with multiple knowledge bases, the KB Knowledge Bases widget provides users with a menu to select a knowledge base. After a user selects a knowledge base, other KB widgets on the page filter their content accordingly.

For example, if a user selects to browse only the IT knowledge base, then the [KB Categories widget](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-user-interface/service-portal/kb-categories-widget.md) shows only the categories within the IT knowledge base.

If you associate your portal with only one knowledge base, then the KB Knowledge Bases widget remains hidden on the page.

For more information on associating your portal with knowledge bases, see [Associate a portal with a knowledge base](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-user-interface/service-portal/associate-portal-knowledge.md).

## Instance options

The KB Knowledge Bases widget doesn't include instance options.
