Returns the control panel nav items.

Each control panel nav item should be defined by an array with the following keys:

• icon – The path to an SVG file that should be used as the nav item icon (optional)
• fontIcon – A character/ligature from Craft’s font icon set (optional)
• badgeCount – A number that should be displayed beside the nav item when unselected
• subnav – A sub-array of subnav items

Subnav arrays should be associative, with identifiable keys set to sub-arrays with the following keys:

• label – The human-facing subnav item label
• url – The URL the subnav item should link to

For example:

[
    'label' => 'Commerce',
    'url' => 'commerce',
    'subnav' => [
        'orders' => ['label' => 'Orders', 'url' => 'commerce/orders',
        'discounts' => ['label' => 'Discounts', 'url' => 'commerce/discounts',

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).

EVENT_REGISTER_CP_SETTINGS

Type

craft\events\RegisterCpSettingsEvent

Since

3.1.0

The event that is triggered when registering links that should render on the Settings page in the control panel.

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

Event::on(Cp::class, Cp::EVENT_REGISTER_CP_SETTINGS, function(RegisterCpSettingsEvent $e) {
    $e->settings[Craft::t('app', 'Modules')] = [
        'label' => 'Item Label',
        'url' => 'my-module',
        'icon' => '/path/to/icon.svg',
    ];
});

craft\events\RegisterCpSettingsEvent::$settings is an array whose keys define the section labels, and values are sub-arrays that define the individual links.

Each link array should 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.
