TYPO3 Core

Using the property cols="inline" doesn't have an effect for checkboxes with renderType checkboxToggle.

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns('tt_content', [
        'checkboxes' => [
            'exclude' => false,
            'label' => 'Checkbox Default',
            'config' => [
                'type' => 'check',
                'cols' => 'inline',
                'items' => [
                    ['label' => 'checkbox item',],
                    ['label' => 'checkbox item',],
                    ['label' => 'checkbox item',],
                    ['label' => 'checkbox item',],
                ],
            ],
        ],
        'checkboxes2' => [
            'exclude' => false,
            'label' => 'Checkbox Toggle',
            'config' => [
                'type' => 'check',
                'renderType' => 'checkboxToggle',
                'cols' => 'inline',
                'items' => [
                    ['label' => 'checkbox item',],
                    ['label' => 'checkbox item',],
                    ['label' => 'checkbox item',],
                    ['label' => 'checkbox item',],

    ]);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToAllTCAtypes('tt_content', 'checkboxes,checkboxes2,checkboxes3');

Expectation: all checkboxes are displayed inline for every checkbox field.

In the class TYPO3\CMS\Backend\Form\Element\CheckboxToggleElement function renderSingleCheckboxElement the variable $inline is setup like in the other 2 checkbox classe but remains unused.

It seems that was removed here: https://review.typo3.org/c/Packages/TYPO3.CMS/+/78547

Suggested fix: either remove it for the other two as well or re-add it for checkboxToggle
