Providing Left Navigation Using PT_SIDE_PAGETABS
Some fluid pages are the only page within a fluid component. In which case, they are standalone, and once an end user arrives at them, there is obviously no need to provide additional navigation devices within the component. However, other fluid components may have multiple pages within a component. You then need to consider how you would like users to navigate through the component.
By default, similar to classic components, the page tabs appear across the top of the page, always visible to the end user.
