The ComboBox component for ReactJS contains an input field with auto-complete functionality and a list of selectable items displayed in a drop-down.

In order to bind to any event, change any property or call any method, we need a reference to the component.
For that we use the ReactJS "ref" Callback Attribute:

This is done in the componentDidMount() ReactJS Component Lifecycle method.
The change event is triggered when the user selects an item.

Every component have a method setOptions which accepts a object as an argument. This object contains component settings.
Every component also have a method getOptions which returns a object containing the component settings.
