## Description

Marks navigation paths with "in-path" and "current" classes.


## Documentation

The "in-path" and "current" classes and the "item-wrapper" are configurable.

You can automatically load the navigation item marked with the `current` class by adding the class `navigation-load-current` along with `pat-navigation` on the pattern element.
This would invoke a `click` event on the current navigation item and that can be used to load content via `pat-inject`.

For examples see index.html.

### Option reference

The navigation pattern can be configured through a `data-pat-navigation` attribute.
The available options are:

| Field           | Default              | Options        | Description                                                                                                                                                            |
