Hi Is there a way of breaking inheritance before creating new list/library so that there is no need to delete all security groups from permissions and create new(my site have lots lots of groups, so not able to delete all groups is not possible in single attempt.) Thanks!!!

Hi, At the time of new site creation it has been asked to inherit permission from parent site or use an unique permission , select unique permission which will break inheritance from parent and you can add unique owners, visitors, members etc. users.Warm Regards, Pratik Vyas | SharePoint Consultant | http://sharepointpratik.blogspot.com/
