You may use expression properties:
The following expression below means: the item is shown if, the same value is checked in the {car} question and it is not selected in the {bestcar} question.
{car} contains {item} and {item}!= {bestcar}
Every ItemValue object has its own visibleIf property. You may override the top level choicesVisibleIf property and define visibleIf expression for an individual choice item.
Help us serve you better by taking this brief survey.
We are interested to learn more about your
experience of using our libraries.
