isItemActive() protected method

This is done by checking if [[route]] and [[params]] match that specified in the url option of the menu item. When the url option of a menu item is specified in terms of an array, its first element is treated as the route for the item and the rest of the elements are the associated parameters. Only when its route and parameters match [[route]] and [[params]], respectively, will a menu item be considered active.

protected isItemActive ( array $item ) : boolean
$item	array	the menu item to be checked
return	boolean	whether the menu item is active

    protected function isItemActive($item)
    {
        if (isset($item['url']) && is_array($item['url']) && isset($item['url'][0])) {
            $route = Yii::getAlias($item['url'][0]);
            if ($route[0] !== '/' && Yii::$app->controller) {
                $route = Yii::$app->controller->module->getUniqueId() . '/' . $route;
            }
            if (ltrim($route, '/') !== $this->route) {
                return false;
            }
            unset($item['url']['#']);
            if (count($item['url']) > 1) {
                $params = $item['url'];
                unset($params[0]);
                foreach ($params as $name => $value) {
                    if ($value !== null && (!isset($this->params[$name]) || $this->params[$name] != $value)) {
                        return false;
                    }
                }
            }
            return true;
        }
