{% if page.sub-nav-group and page.sub-nav-parent != "_root_" %}
{% comment %}
The plain layout with a sub navigation.

- This is activated via the 'sub-nav-group' field in the preemble.
- All pages of this sub nav group will be displayed in the sub navigation:
  * Each element without a 'sub-nav-parent' field will be displayed on the 1st level, where the position is defined via 'sub-nav-pos'.
  * If the page should be displayed as a child element, it needs to specify a 'sub-nav-parent' field, which matches the 'sub-nav-id' of its parent. The parent only needs to specify this if it expects child nodes.
