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.

public string $activeUrl = null
$encodeLabels public property

Whether the nav items labels should be HTML-encoded.

public boolean $encodeLabels = true
$items public property

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: bool, 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: bool, 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.

public array $items = []
