Yii2使用yii2-adminlte+yii2-admin左侧菜单子路径不高亮问题又解。 [ 2.0 版本 ]

兄弟你这个再上个效果图就更好了

放到我的代码里有module的 /module/controller/action路径没问题，如果是没有module的/controller/action路径就只能是全等的时候才高亮。

我增加了一段 如果当前path是2个元素 就是没有module的，比较下标为0也就是第一个元素，如果是3个元素就是有module的，比较下标为1也就是第二个元素

$route = ltrim($route,'/');
$route = explode('/', $route);
$path = explode('/', $this->route);
/*下面是增加的部分start*/
$pathCount=count($path);
if ($pathCount == 2 && $route[0] != $path[0] && $route !== $this->noDefaultRoute && $route !== $this->noDefaultAction) {
    return false;
}
/*上面是增加的部分end*/
//下面要判断$pathCount==3
if ($pathCount == 3 && $route[1] != $path[1] && $route !== $this->noDefaultRoute && $route !== $this->noDefaultAction) {
    return false;
}

官方最新版本（2.6.0）已经解决了这个问题，可以达到子菜单级别的高亮：
` /**

 * Checks whether a menu item is active.
 * 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.
 * @param array $item the menu item to be checked
 * @return boolean whether the menu item is active
 */
protected function isItemActive($item)
{
    if (isset($item['url']) && is_array($item['url']) && isset($item['url'][0])) {
        $route = $item['url'][0];
        if ($route[0] !== '/' && Yii::$app->controller) {
            $route = ltrim(Yii::$app->controller->module->getUniqueId() . '/' . $route, '/');
        }
        $route = ltrim($route, '/');
        if ($route != $this->route && $route !== $this->noDefaultRoute && $route !== $this->noDefaultAction) {
            return false;
        }
        unset($item['url']['#']);
        if (count($item['url']) > 1) {
            foreach (array_splice($item['url'], 1) as $name => $value) {
                if ($value !== null && (!isset($this->params[$name]) || $this->params[$name] != $value)) {
                    return false;
                }
            }
        }
        return true;
    }
    return false;
}`
