Top-level navigation for Website Releases can be set to either Expanded or Compact view.
Expanded view displays navigation items in a horizontal list with vertical fly outs.
With this setting, website navigation items will display horizontally below the header area and above the content of your page.
If the navigation item contains sub-items, those will open into a vertical list beneath the top-level item.
If the sub-items contain additional items, an arrow will appear to the right that when clicked, toggles the list to those items.
Compact view will display a single item as top-level navigation beneath the header area that opens a list view containing sub-items.
If the sub-items contain additional items, an arrow will appear to the right that when clicked, toggles the list to those items.
