When I perform a Mass Update on triggers, then select "Add" for trigger dependencies, the popup drop-down for "Group" only contains groups that have monitored hosts. All templates are in their own Host Group and they are not visible in the pop up.

I noticed the "Add" link had the following javascript.

PopUp("popup.php?dstfrm=massupdate&dstact=add_dependency&reference=deptrigger&dstfld1=new_dependency[]&srctbl=triggers&objname=triggers&srcfld1=triggerid&multiselect=1&monitored_hosts=1&with_triggers=1", 1000, 700)

If I modify "monitored_hosts=1" to "monitored_hosts=0" , and execute that java script in a javascript console, the popup produced contains all host groups in the "Group" dropdown.

I am running Zabbix 2.2.1
