Ability to restrict users (vendors) from creating new tags

Hello,

Unfortunately, HikaMarket is using the Joomla tag element to perform the selection of the tags ; that element allows to pick-up and to create new tags on the fly and that is done directly by Joomla core.
It would need to check when the tag is created exactly but, adding a restriction on that would be very complicated since it would require to create specific code to handle parts which are in the Joomla core so it could see to remove tags which do not exists...
But since all the system is in the Joomla core and the UCM system, it's not very easy to have control on that (and clearly, we don't want to perform the insertion manually since it changed between Joomla 3 versions)

If you want to have the control on tags, I would rather recommend to use an HikaShop custom field to perform a similar feature.

Hello,

I can't tell you much about the Joomla ACL and how they are manage, but I assume it's regarding the controller and not the help itself.
HikaMarket do nothing regarding the tags ; it just uses the HikaShop tags helper which have an interface with the Joomla UCM system and use the "JHelperTags" to perform preStorageProcess and postStorageProcess.
All HikaShop is doing is to providing an object which feet the requirements of the JHelperTags and the Joomla core is doing the rest.

Now when you're trying to create a new tags, the system do not create the tags on the fly but they are using special values so the JHelperTags will create them during the save.
Why the ACL are not used, I can't tell you but if you do not want to authorize the creation of tags ; the fast solution would be to use a custom plugin with onBeforeProductCreate/onBeforeProductUpdate to remove the unwanted entries in " $element->tags ".
