Hi jcata,
You are right. There is still a bug on selecting VM sub-categories in the backend of our JA VM Products module. In order to solve this issue, you need to open modulesmod_javmproductsassetselementsvmcategories.php, the replace line (112th):
self::categoryListTreeLoop ($selectedCategories, $childId, $level, $disabledFields);
with
$categoryTree .= ShopFunctions::categoryListTreeLoop ($selectedCategories, $childId, $level, $disabledFields);
Save. You can select & display the VM sub-categories then. We will include this bug fix of JA VM Products module in next update of quickstart version.
@moon Sailer: Thank for your tip !
