You may use expression properties:

  • choicesVisibleIf in radio group, checkbox and dropdown questions.
  • columnsVisibleIf and rowsVisibleIf in matrix question
  • and rowsVisibleIf in matrix dropdown question
to hide/show choices items, columns and rows in these questions. The expression runs against each choices item. To get the current item value, please use {item} variable in your expression.

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.
