Filter list

hi
i want filter a CB list to show users according my usergroup. for example if UserA in userGroupA and userGroupB he must see all users in userGroupA&B and if UserD registred  in usergroup C he must see all user in usergroupC. how to do that with one list? how to implement with CB list filter(Advanced or basic)? 
i understand in Global tab we have Usergroups setting but in that setting we have not setting like "current usergroup" .

Add a subquery against _user_usergroup_map based off whatever criteria you need to the advanced filter. Sorry, I cannot help you with custom coding without a business membership .

thank you but i need only understand how to get current user usergroup? each user must see his teammate (users with he in same usergroup.) is there any substitution to return current usergroup number? i can use advanced and write custom sql for my need but i can not get current user usergroup code. it seems according tool tip of advanced filter, i can not use php and only can use sql.

There is, but it's complicated. You can use [gids] but it will be an array converted to a string with values separated by |*|. It's usually best to use the IF substitutions to check for usergroups as it deals with the array handling for you. Example as follows.

[cb:if usergroup includes "2"]I have Registered Usergroup[/cb:if]

Correct, you cannot use PHP there only SQL. That will directly add to the WHERE statement of the query.
