Regions

The Regions node is used to display a list of regions.

At the top of the Regions node is a pin that allows it to connect to a parent widget. The region will be displayed only, if a parent connection is made.

At the bottom of the Regions node is a pin that allows it to connect children to the regions widget. The parent, grandparent, children and grandchildren define the layering of the widgets and the graphical outcome.

Children are layered on top of the parent.
