The dropdown «Page Layout» on admin category page is untranslatable due to Magento 2 core bug:
The options are defined in
The wrong code is:
It totally ignores translate
attribute of label
tag.
My fix is replace the wrong line with the code:
/** @var string $label */
$label = trim($layout->nodeValue);
if ('true' === (string)simplexml_import_dom($layout)->{'label'}['translate']) {
$label = __($label);
}
$result[$layout->getAttribute('id')] = $label;
