Hello,
UPDATE: phpdocx 10 added support to apply custom list styles with ol and ul tags.
Please follow the following steps:
1. Edit CreateDocx.php (Classes/Phpdocx/Create folder in the namespaces package).
2. embedHTML method.
3. Replace the following line:
if (isset($value['attributes'])) {
by:
if (isset($value['attributes']) && $newNumberingDOM) {
That allows adding customListStyles with ol tags.
Regards.
