Is there any way in alfresco to create a taggroups, like alfresco provides creating a tags for nodes If a user want to add a tags on nodes he need to give the tags everytime instead of that can he create a taggroup and apply tag group to node so that all tags in that group can attach to node. Any ideas how to implement it can be helpful
Nothing out of box. You need to customize it.Or else you can use categories where you have facility to create sub categories but mind it both of them have different idea behind them.
