Steps to reproduce

1. Set up a NavigationMenu component with nested items.
2. Create at least two levels of submenu items.
3. Trigger the second-level submenu item.

Describe the bug

When the NavigationMenu contains nested items, the submenu items of a submenu item are not shown. This makes it impossible to navigate deeper into the menu structure.

Expected behavior

When a submenu item is triggered, its nested submenu items should appear.
