is_child_of (path, strict=False)

This method is a convenient way to check if a page is a child of another page or not. The default behavior is to consider a page to be a child of itself as this is more convenient in most situations but this can be changed with the strict parameter. This method is particularly useful when building a navigation.


<a href="{{ '/projects'|url }}"{% if this.is_child_of('/projects')
  %} class="active"{% endif %}>Projects</a>
