CheckBox visibility Function

hi, Please go through below sample code and you can modify according to your requirements. The idea here is to configure the "showWhen" parameter of the text field. configure this parameter with a boolean variable which gets changed based on checkbox selection.

a!localVariables(
  local!selectedChoice:false,
  {
    a!checkboxField(
      label: "checkbox",
      choiceLabels: {"Yes","No"},
      choiceValues: {true,false},
      value: local!selectedChoice,
      saveInto: local!selectedChoice
    ),
    a!textField(
      label: "text field",
      showWhen: local!selectedChoice
    )
  }
)

hi, if you want to display specific box or multiple boxes while selecting the check box, then you can modify the below code as you desire.

a!localVariables(
  local!selectedBox,
  {
    a!checkboxField(
      choiceLabels: { "a", "b" },
      choiceValues: { 1, 2 },
      value: local!selectedBox,
      saveInto: local!selectedBox,

    ),
    a!textField(
      showWhen: {
        and(
          a!isNotNullOrEmpty(local!selectedBox),
          local!selectedBox = 1
        )
      },
      label: "text field 1"
    ),
    a!textField(
      showWhen: {
        and(
          a!isNotNullOrEmpty(local!selectedBox),
          local!selectedBox = 2
        )
      },
      label: "text field 2"
    )
  }
)
