This example overrides the crop variants in a configured fal relation:

'assets' => [
    'config' => [
        'overrideChildTca' => [
            'columns' => [
                'crop' => [
                    'config' => [
                        'cropVariants' => [
                            'default' => [
                                'disabled' => true,
                            ],
                            'mobile' => [
                                'title' => 'LLL:EXT:ext_key/Resources/Private/Language/locallang.xlf:imageManipulation.mobile',
                                'cropArea' => [
                                    'x' => 0.1,
                                    'y' => 0.1,
                                    'width' => 0.8,
                                    'height' => 0.8,
                                ],
                                'allowedAspectRatios' => [
                                    '4:3' => [
                                        'title' => 'LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.4_3',
                                        'value' => 4 / 3
                                    ],
                                    'NaN' => [
                                        'title' => 'LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.free',
                                        'value' => 0.0
                                    ],
                                ],
                            ],
                        ],
                    ],
                ],
            ],
        ],
    ],
],

This example overrides the showitem field of the child table TCA:

'anInlineField' => [
    'config' => [
        'type' => 'inline',
        'overrideChildTca' => [
            'types' => [
                'aForeignType' => [
                    'showitem' => 'aChildField',
                ],
            ],
        ],
    ],
],

This overrides the default columns property of a child field in an inline relation from within the parent if a new child is created:

'anInlineField' => [
    'config' => [
        'type' => 'inline',
        'overrideChildTca' => [
            'columns' => [
                'CType' => [
                    'config' => [
                        'default' => 'image',
                    ],
                ],
            ],
        ],
    ],
];

This overrides the foreign_selector field target field config, defined in the foreign_selector property. This is used in FAL inline relations:

'anInlineField' => [
    'config' => [
        'type' => 'inline',
        'foreign_selector' => 'uid_local',
        'overrideChildTca' => [
            'columns' => [
                'uid_local' => [
                    'config' => [
                        'appearance' => [
                            'elementBrowserType' => 'file',
                            'elementBrowserAllowed' => $allowedFileExtensions
                        ],
                    ],
                ],
            ],
        ],
    ],
],

Note

It is allowed to use this property within the columnsOverrides property of an inline parent in the ['types'] section.
