Hello I use virtuemart 3.2. In the drop down menu using variants I would like the child products that are not in stock to have a red font color or be inactive. I think this is essential for virtuemart. Can anyone guide me where is the php file that i should customize.
think "type A' in around components\com_virtuemart\sublayouts\customfield.php ~ line 298
foreach ($uncatChildren as $k => $child) {
which forms the options for the select - over ride the file
