# Breaking: #64190 - FormEngine Checkbox Element limitation of cols setting {#breaking-64190-formengine-checkbox-element-limitation-of-cols-setting}

See [forge#64190](https://forge.typo3.org/issues/64190)

## Description {#description}

The TCA configuration for checkbox cols has been changed. We reduced the
number of accepted values to 1, 2, 3, 4 and 6 to provide a responsive experience.

For usecases like checkboxes for weekdays like mo, tu, we, th, fr, sa, su
we introduced a new value `inline`.

## Impact {#impact}

For values equals 5 or above 6 the rendering of 6 will be used.

## Affected installations {#affected-installations}

Installations with TCA column configurations for checkboxes with values
equals 5 or above 6.

## Migration {#migration}

Choose between one of the supported values or change the display to `inline`.
