Page Builder now supports dependent picklists. When a picklist field is configured with a controlling field in the data model, its options are filtered to show only the values that are valid for the current controlling field value.
How it works
Available on both create and edit pages built with Page Builder.
As the controlling field changes, the dependent picklist updates immediately to reflect the new valid options.
If the user has already selected a value that's no longer valid, the dependent field is cleared automatically.
