Step-by-Step Guide to TYPO3 Custom Elements


Step 1. PageTSconfig: Tab Registration of the TYPO3 “Custom Elements”

// typo3conf/myextension/Configuration/PageTSconfig/setup.typoscript


mod.wizards.newContentElement.wizardItems.extra {
    header = Custom Elements
    icon =
    elements {
        myextension_newcontentelement {
            iconIdentifier = my-icon-identifier
            title = LLL:EXT:my/Resources/Private/Language/Tca.xlf:myextension_newcontentelement.wizard.title
            description = LLL:EXT:myextension/Resources/Private/Language/Tca.xlf:myextension_newcontentelement.wizard.description
            tt_content_defValues {
                CType = myextension_newcontentelement
    show := addToList(myextension_newcontentelement)

// typo3conf/ext/myextension/ext_localconf.php


$iconRegistry = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Core\Imaging\IconRegistry::class);
// use same identifier as used in TSconfig for icon
   // use same identifier as used in TSconfig for icon
   // font-awesome identifier ('external-link-square')
   ['name' => 'external-link-square']


Step 2. TCA tt_content: Add TYPO3 Custom Elements to “Type” Dropdown

// typo3conf/myextension/Configuration/TCA/Overrides/tt_content.php




Step 3. TCA tt_content: Add Fields

// typo3conf/myextension/Configuration/TCA/Overrides/tt_content.php


$GLOBALS['TCA']['tt_content']['types']['myextension_newcontentelement'] = [
    'showitem' => '
    'columnsOverrides' => [
        'bodytext' => [
            'config' => [
                'enableRichtext' => true,
                'richtextConfiguration' => 'default',


Step 4. TCA sys_template: Include Frontend Template

// typo3conf/myextension/Configuration/TCA/Overrides/sys_template.php


    'My description of template'


Step 5. TypoScript: Register TYPO3 Custom Element

// typo3conf/myextension/Configuration/TypoScript/setup.typoscript


tt_content {
    myextension_newcontentelement =< lib.contentElement
    myextension_newcontentelement {
        templateName = NewContentElement


Step 6. Fluid: Render TYPO3 Custom Element

// typo3conf/myextension/Resources/Private/Templates/NewContentElements.html/


<html data-namespace-typo3-fluid="true"
<h2>Woohoo! My First TYPO3 Custom Element</h2>
<div class=”container”>
{data.bodytext -> f:format.html()}


Step 7. (Optional) Do you want a cool Backend Preview?

// typo3conf/myextension/ext_localconf.php


// Register for hook to show preview of tt_content element of CType="myextension_newcontentelement" in page module
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem']['myextension_newcontentelement'] =


// typo3conf/myextenison/Classes/Hooks/PageLayoutView/NewContentElementPreviewRenderer.php


namespace Vendor\MyExtension\Hooks\PageLayoutView;
use TYPO3\CMS\Backend\View\PageLayoutView;
use TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface;
class NewContentElementPreviewRenderer implements PageLayoutViewDrawItemHookInterface
     * Preprocesses the preview rendering of a content element of type "My new content element"
     * @param \TYPO3\CMS\Backend\View\PageLayoutView $parentObject Calling parent object
     * @param bool $drawItem Whether to draw the item using the default functionality
     * @param string $headerContent Header content
     * @param string $itemContent Item content
     * @param array $row Record row of tt_content
     * @return void
    public function preProcess(
        PageLayoutView &$parentObject,
        array &$row
    ) {
        if ($row['CType'] === 'myextension_newcontentelement') {
            $itemContent .= '<p>We can change our preview here!</p>';
            $drawItem = false;


Step 8. (Optional) Using TYPO3 Data Processor Concepts

Data processors can be used for some data manipulation or other actions you would like to perform before passing everything to the view.

// typo3conf/myextension/Configuration/TypoScript/setup.typoscript


tt_content {
    myextension_newcontentelement =< lib.contentElement
    myextension_newcontentelement {
        templateName = NewContentElement
        dataProcessing {
            1 = Vendor\MyExtension\DataProcessing\NewContentElementProcessor
            1 {
                exampleOptionName = exampleOptionValue


// typo3conf/Classes/DataProcessing/NewContentElementProcessor.php


declare(strict_types = 1);
namespace Vendor\MyExtension\DataProcessing;
class NewContentElementProcessor implements DataProcessorInterface
     * Process data for the content element "My new content element"
     * @param ContentObjectRenderer $cObj The data of the content element or page
     * @param array $contentObjectConfiguration The configuration of Content Object
     * @param array $processorConfiguration The configuration of this processor
     * @param array $processedData Key/value store of processed data (e.g. to be passed to a Fluid View)
     * @return array the processed data as key/value store
    public function process(
        ContentObjectRenderer $cObj,
        array $contentObjectConfiguration,
        array $processorConfiguration,
        array $processedData
    ) {
        $processedData['variableName'] = 'This variable will be passed to Fluid';
        return $processedData;


// typo3conf/myextension/Resources/Private/Templates/NewContentElements.html/


<html data-namespace-typo3-fluid="true"
<h2>Yeah! My First TYPO3 Custom Element with DataProcessing</h2>
<div class=”container”>
    {data.bodytext -> f:format.html()}
