The verified answer is the Conditional View property on a Step or Block element. In OmniScript, conditional display logic is used to hide or show an element, a group of elements, a block, or a step based on user input or other data conditions. This directly satisfies the requirement to control pages or groups of fields based on choices made by the user. Creating child OmniScripts is excessive for normal branching visibility. Radio Input is only an input control; it can provide the selected value, but it does not itself control page or field visibility. 'Visibility Rules' is not the precise OmniStudio property name used in the official documentation for this function.
