The component supports the three state mode. In this demo, the enableThreeStateBehavior property of the "Three state mode" JavaScript CheckBox is enabled. You can cycle through the states of this JavaScript CheckBox in the following order:

Indeterminate → Checked → Unchecked → Indeterminate → ...

Specify the onValueChanged property to handle value changes. In this demo, the value of the "Handle value change" JavaScript CheckBox is passed to the "Disabled" JavaScript CheckBox. Click the first JavaScript CheckBox to see how it affects the second one.

You can use the iconSize property to specify custom dimensions for the JavaScript CheckBox. To add a label to the JavaScript CheckBox, specify the text property.
