Trigger: Show After Inactivity (Pro)
Want a popup to show only when someone is on your website but doesn't do anything on it for a while? You can do this.
When editing your popup, you will want to go into Triggers.
In Edit Triggers, you can turn on Show After Inactivity. Once on you will enter the number of seconds that you want HollerBox to wait for before it shows the popup.
When you are ready to show it off to the world, you can close Edit Triggers (top-right corner), then save / publish your popup.
