This page is for application designers who need to apply a background filter to the data that is displayed from table.

The following layout components display data from a record:

  • a view
  • a card container.

In some cases, you may need to apply a filter on the table data that is displayed in the view or card container. This is called a background filter. The layout properties enable to you select several filter rules that combine to form a background filter.  This page explains how to set up a filter rule.

This properties tab is not available from the repository. It opens from the layout properties → Background Filter Rules section.

For information about the properties toolbar, and about the sections Parent Details, Analysis Models, Description and Audit Summary, see Common Properties.  We recommend you always add a Description that explains the purpose of the item you are creating. 

For a full list of all the PhixFlow property tabs and windows, see Properties, Windows, Menus and Toolbars.
