In this example, the markup for an options widget is being wired up by an instance of Uize.Widget.Options. Below the options are some links that execute snippets of code to demonstrate the programmatic interface of the widget. The Uize.Widget.Options class provides value and tentativeValue state properties in its interface. The Changed.value and Changed.tentativeValue instance events for these two properties can be used to watch for changes in the widget's state. The value state property can be set to programmatically change the selected option. Interact with both the options UI and the test links to see how they affect one another.
