Trigger Groups

Trigger Group is the newest trigger type you can add to a tag in Google Tag Manager. It allows you to establish dependencies between multiple triggers, not firing the tag until every trigger in the group has fired at least once.

This establishes an interesting new paradigm in Google Tag Manager, because until now it wasn’t possible to create triggers that relied on earlier values of a given key (event in this case). With the Trigger Group, information about triggers that have fired on the page is persisted internally in GTM, and once the triggers configured in the Trigger Group have all signalled completion, the Trigger Group will fire any tag it’s attached to.
