Load on Demand
Set EnableOnDemand as true to enable load tab and backstage contents dynamically. Loading content on demand improves the initial rendering time of the ribbon by rendering tab and backstage content when tabs and backstage items are clicked.

Initially Collapsible
Set Collapsible as true to render ribbon control in collapsed state, which results ribbon tabs to render without any content initially.
While using initially collapsible ribbon with EnableOnDemand feature improves the performance by reducing initial loading time of ribbon.
