Select one and cascading with ODK Build

[jojo]

How can I make a dynamic selection with select one question in ODK BUILD? I want the select one options to be shown depending on a previous choice choice.

On the first question, tick the check box for "Cascading"

In the second question, there will be an additional field for each answer option. Use the "Underlying Value" from the first set of options to filter the second set.
