Nav renders a nav HTML component.
For example:
echo Nav::widget([
'items' => [
[
'label' => 'Home',
'url' => ['site/index'],
'linkOptions' => [...],
],
[
'label' => 'Dropdown',
'items' => [
['label' => 'Level 1 - Dropdown A', 'url' => '#'],
'<li class="divider"></li>',
'<li class="dropdown-header">Dropdown Header</li>',
['label' => 'Level 1 - Dropdown B', 'url' => '#'],
],
],
],
]);
Note: Multilevel dropdowns beyond Level 1 are not supported in Bootstrap 3.

Whether the nav items labels should be HTML-encoded.
List of items in the nav widget. Each array element represents a single menu item which can be either a string or an array with the following structure:
- label: string, required, the nav item label.
- url: optional, the item's URL. Defaults to "#".
- visible: boolean, optional, whether this menu item is visible. Defaults to true.
- linkOptions: array, optional, the HTML attributes of the item's link.
- options: array, optional, the HTML attributes of the item container (LI).
- active: boolean, optional, whether the item should be on active state or not.
- items: array|string, optional, the configuration array for creating a Dropdown widget, or a string representing the dropdown menu. Note that Bootstrap does not support sub-dropdown menus.
If a menu item is a string, it will be rendered directly without HTML encoding.
