A filter applied to a parent page and all of its child pages.
A cascaded filter is a Targeted Search filter that, when right-clicked in the label application window, is applied to that page and all of its child pages. This is done automatically by Targeted Search. Any child pages created after this action will also have the cascaded filter applied.
To differentiate them from normal filters, cascaded filters are shown with a pink background color on the parent page and purple background color on child pages.
