How to show the colpos id after the name in TYPO3 Backend layout?

Question

I have a need to show for tt_content records the id of the colpos for regular editors on the production website, for now it is only shown in my development space website.

do you have an idea how to add it ? Thank you!

You can add a custom itemsProcFunc for the select field which is used for the colPos column here. Use TCA overrides to register it accordingly:

\TYPO3\CMS\Core\Utility\ArrayUtility::mergeRecursiveWithOverrule(
    original: $GLOBALS['TCA']['tt_content'],
    overrule: [
        'columns' => [
            'colPos' => [
                'config' => [
                    'itemsProcFunc' => \VENDOR\Extension\UserFunction\FormEngine\ItemProcessor::class . '->appendValueToLabel',
                ],
            ],
        ],
    ],
);

The ItemProcessor class:

<?php
declare(strict_types = 1);

namespace VENDOR\Extension\UserFunction\FormEngine;

final class ItemProcessor
{
    public function appendValueToLabel(array &$params): void
    {
        foreach ($params['items'] as &$item) {
            $item['label'] = sprintf('%s [%s]', $item['label'], $item['value']);
        }
    }
}
