Events

EVENT_REGISTER_CP_NAV_ITEMS

Type

craft\events\RegisterCpNavItemsEvent

The event that is triggered when registering control panel nav items.

use craft\events\RegisterCpNavItemsEvent;
use craft\web\twig\variables\Cp;
use yii\base\Event;

Event::on(
    Cp::class,
    Cp::EVENT_REGISTER_CP_NAV_ITEMS,
    function(RegisterCpNavItemsEvent $e) {
        $e->navItems[] = [
            'label' => 'Item Label',
            'url' => 'my-module',
            'icon' => '/path/to/icon.svg',
        ];
    }
);

craft\events\RegisterCpNavItemsEvent::$navItems is an array whose values are sub-arrays that define the nav items. Each sub-array can have the following keys:

• label – The item’s label.

• url – The URL or path of the control panel page the item should link to.

• icon – The path to the SVG icon that should be used for the item.

• badgeCount (optional) – The badge count number that should be displayed next to the label.

• external (optional) – Set to true if the item links to an external URL.

• id (optional) – The ID of the <li> element. If not specified, it will default to nav-.

• subnav (optional) – A nested array of sub-navigation items that should be displayed if the main item is selected.

  The keys of the array should define the items’ IDs, and the values should be nested arrays with label and url keys, and optionally badgeCount and external keys.

If a subnav is defined, subpages can specify which subnav item should be selected by defining a selectedSubnavItem variable that is set to the selected item’s ID (its key in the subnav array).
