On V4, the widget/template screens have been rolled into a single area called "Regions". Regions are a means of reusing content that should appear on more than a single page, for example a header or footer. There are six different regions:
- Header
- Hero
- Above Content
- Content
- Below Content
- Footer
The "Content" region is a way to create a boilerplate for displaying different post types. For example you may want to create a page layout to be reused for all team posts. By associating a layout with this region you can setup a page layout once and have it applied to all team posts.
Visibility Conditions
Layouts in each region may have Visibility Conditions applied to them. Only one layout will be used from each region, the first layout to match the visibility conditions will be selected, starting from the top of the list. If you specify a layout at the top of the list to be displayed on a specific page, there's no need to adjust the visibility conditions on the remaining layouts, V4 will pick the first layout that matches the conditions and ignore the rest.
