Twig templates - Page template functions {{ fn.* }}

The following custom Twig functions can be used within page templates (Themes > Templates):

navigation(attributes_json)

Outputs navigation menus.

{{ fn.navigation({"group":"Primary navigation","levels":1,"template":"Primary navigation"}) }}

The attributes JSON string accepts the following properties:

1. page_id - Integer - The child pages of the specified page's ID will be output as the top level of the navigation.
2. group - String - Use in place of page_id to display the pages of one of the site tree's page groups (e.g. "Primary navigation").
3. template - Integer | String - The ID or title of the content template (Themes > Content templates) to use to output the navigation's HTML.
4. use_siblings - Boolean - If a page_id is specified, use_siblings will set the navigation to use the specified page and it's siblings as the top level of the navigation, instead of the page's children.
5. levels - Integer - Default: 0 - The number of levels deep in the page heirarchy to output. For example, a setting of 1 will output the root level and one level deep, useful for drop down menus. 

redirect(status_code = 404, url) 

Allows the template to force a header redirect to another URL before the page has completed processing.

{{ fn.redirect(301, 'http://example.com') }}

template(template)

Outputs the content of another template.

Example: {{ fn.template('Document head') }}
