DocHeaderComponent 

The \TYPO3\CMS\Backend\Template\Components\DocHeaderComponent can be used to display a standardized header section in a backend module with buttons, menus etc. It can also be used to hide the header section in case it is not desired to display it.

The module header displayed by the DocHeaderComponent

You can get the DocHeaderComponent with \TYPO3\CMS\Backend\Template\ModuleTemplate::getDocHeaderComponent from your module template.

Example: Build a module header with buttons and a menu 

The following example is extracted from the example Extbase extension t3docs/blog-example . See the complete source code at t3doc/blog-example (GitHub).

We use the DocHeaderComponent to register buttons and a menu to the module header.

Class T3docs\BlogExample\Controller\BackendController 
<?php

use Psr\Http\Message\ServerRequestInterface;
use TYPO3\CMS\Backend\Template\ModuleTemplate;

class BackendController extends ActionController
{
  private function modifyDocHeaderComponent(ModuleTemplate $view, string &$context): void
  {
    $menu = $this->buildMenu($view, $context);
    $view->getDocHeaderComponent()->getMenuRegistry()->addMenu($menu);

    $buttonBar = $view->getDocHeaderComponent()->getButtonBar();
    $this->addButtons($buttonBar);

    $metaInformation = $this->getMetaInformation();
    if (is_array($metaInformation)) {
      $view->getDocHeaderComponent()->setMetaInformation($metaInformation);
    }
  }

  protected function initializeModuleTemplate(
    ServerRequestInterface $request,
  ): ModuleTemplate {
    $view = $this->moduleTemplateFactory->create($request);

    $context = '';
    $this->modifyDocHeaderComponent($view, $context);
    $view->setFlashMessageQueue($this->getFlashMessageQueue());
    $view->setTitle(
      $this->getLanguageService()->sL('LLL:EXT:blog_example/Resources/Private/Language/Module/locallang_mod.xlf:mlang_tabs_tab'),
      $context,
    );

    return $view;
  }
}
