WPML support

Actually no. Because we have our own system of translation.
You can configure it.

You can translate product fields, labels, drop-down items and fields.

To translate a language just create or edit a file (e.g: “en_US.php”, “fr_FR.php”, “it_IT.php”) in: “/wp-content/uploads/woo-price-calculator/translations”

EX.
For example “en_US.php”:

<?php
return array(
	'height' => 'Height',
	'width' => 'Width',
);

For example “it_IT.php”:

<?php
return array(
	'height' => 'Altezza',
	'width' => 'Larghezza',
);
