You can group and post different values with the same "name".
When posted to PHP, all checked boxes' values will appear under
the "peripherals" element in `$_POST` array.
E.g. if we check "screen" & "keyboard" and post the form then
`$_POST` will contain `['peripherals' => ['screen', 'keyboard']]`
-->
