Altering the page title

With contextual filters, you have the ability to manipulate the current page's title. When adding or editing a contextual filter, you can modify the page title. You may check the Override title option in When the filter value is present in the URL or a default is provided section.

This textbox allows you to enter in a new title that will be displayed. Additionally, you can use the information passed from the route context using the format of %#, where # is the argument order.
