Custom dropdown menu

gbin2265 · November 2, 2025, 1:14pm

Does anyone know if it’s possible to create a custom dropdown menu and place it on every icingadb page next to the existing dropdown and the refresh button?"

I don’t think there’s a icingadb hook available that would allow this.

Or is there another way to do this?

I would like to place a similar menu with custom items next to it.

Hi! You need to create your own Icinga Web Module for this. I looked a bit around the code and found this: icingaweb2/library/Icinga/Web/Widget/Tabextension/Tabextension.php at 9b639285732ffd4de48ac488e13981eb83d9129b · Icinga/icingaweb2 · GitHub

I am not a Developer, so i cant really help you with the Implementation of this - but maybe it gives you an idea. I also know of a few Icinga Web Module Developers here in the Community
Also, the Youtube Series by my Colleague Markus is a great start: https://www.youtube.com/watch?v=Al4e4bkumsY&list=PLVDjq9pYkysDUk0imvEGDg5TpybsLHiUh&index=3

the problem is that the Tabextension is not a hook.

github.com/Icinga/icinga-php-library

vendor/ipl/web/src/Widget/Tabs.php

a00439f66


      
           *
           * @return $this
           */
          public function setRefreshUrl(Url $url)
          {
              $this->refreshUrl = $url;
          
              return $this;
          }
          
          protected function assemble()
          {
              if ($this->legacyExtensionsEnabled) {
                  $this->tabs->extend(new OutputFormat(
                      $this->dataExportsEnabled
                          ? []
                          : [OutputFormat::TYPE_CSV, OutputFormat::TYPE_JSON]
                  ))
                      ->extend(new DashboardAction())
                      ->extend(new MenuAction());
              }

You would provide this with $this->getTabs()->extend(new YourTabExtension()).

and needs to be called in the Controller.

So one option for me would be override the route and redirect the action to my controller which inherits the DowntimesController and here can call the getTabs() and add my extension.

here is an example how it can be done in the monitoring module:

or:

since all controller inherit from:

github.com/Icinga/icingadb-web

library/Icingadb/Web/Controller.php

main

<?php

/* Icinga DB Web | (c) 2020 Icinga GmbH | GPLv2 */

namespace Icinga\Module\Icingadb\Web;

use Exception;
use Generator;
use GuzzleHttp\Psr7\ServerRequest;
use Icinga\Application\Config;
use Icinga\Application\Icinga;
use Icinga\Application\Logger;
use Icinga\Application\Version;
use Icinga\Application\Web;
use Icinga\Data\ConfigObject;
use Icinga\Date\DateFormatter;
use Icinga\Exception\ConfigurationError;
use Icinga\Exception\Http\HttpBadRequestException;
use Icinga\Exception\Json\JsonDecodeException;
use Icinga\Module\Icingadb\Common\Auth;

you could add your code directly here inherit the init() → call the parent::init() and do the tabs stuff here.

these changes can break icingadb-web or can be reverted during an update but it instantly affects every icingadb tab

I’ll give it a try based on your information.

Thank you!
