Check box

Presents two check boxes, and users can select one.

Data binding

Set or modify the data binding for Check box in the General properties. The view is bound to a Boolean variable.

Configuration properties

Under Behavior, set or modify the configuration properties for Check box.

Screen size: A configuration property that has the Screen Sizes icon beside the property name can have different values for each screen size. If you do not set a value, the screen size inherits the value of the next larger screen size as its default value. If you are using the Process Designer desktop editor (deprecated), you are setting the value for the large screen size. The other screen sizes inherit this value.

Events

Set or modify the event handlers for the view in the Events properties. You can set events to be triggered programmatically or when a user interacts with the view. For information about how to define and code events, see User-defined events. Check box has the following types of event handlers:

On load: Activated when the page loads. For example:
```
me.setChecked(false);
```
On change: Activated when the bound data changes, such as when the box is selected. For example:
```
me.isChecked() ? ${Section1}.setVisible(true) : ${Section1}.setVisible(false);
```

Depending on the specific event, you can use JavaScript logic to modify the effects of the view. More information on using events with views is found in the topic User-defined events.
