Dear Stéphane,
I have created custom meta field for WooCommerce product with some options to select:
‘/gab.’
‘/m.’
‘/iepak.’
‘/kompl.’
below is is Code Snippet I used for this. Now I want them to be translated. Please advise on translating those strings
// Meta Box Class: ProductUnitOfMeasureMetaBox
// Get the field value: $metavalue = get_post_meta( $post_id, $field_id, true );

'post',

'gab.',
'm.',
'iepak.',
'kompl.',
