UXL_V12--20 Alpha Five V12 List control cascading lists Part 1 and 2

When you define multiple List controls on a UX component, you can specify that a List has a "parent" List. If a List has a "parent" List, the data shown in the List is automatically refreshed and filtered every time the current selection in the parent List is changed. There is no limit to the depth of cascading Lists that you can define. In this video, we show how you can define two Lists - one for Countries and one for Cities, and how the data in the Cities list is automatically filtered when the selected Country changes. We then add a third list for Companies, showing the companies in the selected City.
