# Binary option input

A binary option interaction item is used when the operator needs to choose between two values. For example; they are used in conjunction with a decision step to allow the operator to pick a path through the workflow.

Binary option input has the following properties:

* **Target Variable**\
  The name of the new variable in which to store the chosen value of either option 1 or 2.
* **Option 1 text**\
  The text to be displayed for option 1.
* **Option 2 text**\
  The text to be displayed for option 2.
* **Condition To Hide**

  Add the condition that must be met for the control to be hidden. If left empty, the control will be visible in the user step. Note that when controls are hidden, empty variables will be created, unless default values or pre-defined data exist.
* **Option 1 value**\
  The value that should be put into the target variable for the option 1.
* **Option 2 value**\
  The value that should be put into the target variable for the option 2.
* **Refuse option 1**\
  The operator is only allowed to move forward through the workflow if he/she chooses the second option.
* **Default value**\
  Enter a default value (value of option 1 or 2) as a default value.
* **Merge behavior**
