The NavigationBar component for ReactJS is a versatile component for building collapsible side-menu systems. It has header and content sections(like tabs).

The NavigationBar component for ReactJS requires the following imports.
Then we create our component class. Properties and methods are put as ReactJS props.
Finally we render our class in the desired HTML element:
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:
Now, when we have a reference, we need to call the desired event/property/method.
This is done in the componentDidMount() ReactJS Component Lifecycle method.
The collapsingItem event is triggered when a NavigationBar item is going to be collapsed.

Every component also have a method getOptions which returns a object containing the component settings.
