Enterprise ready React NavigationBar component
The NavigationBar for React is a vertical list of selectable items. When you select an item the content of the item is displayed either below or above the bar with the item. The component supports single or multiple expanded items. To switch between the two modes, you need to change the property 'expandMode'. By default, the NavigationBar can have only one expanded item (like Accordion). If the 'expandMode' property value is 'multiple', users can expand or collapse multiple items at the same time.
