Overview
As we've discussed before, Layers are powerful tool for targeting your content to particular audiences or customer segments.
For example, you may have 3 different banner images advertising current promotions on your home page. Using layers and Static Content widgets with layers, you might show one banner to your Government customers, another to Education users, and still another to users in the B2C space.
In some scenarios, you may have users who fall into more than one of these customer groups. When this occurs, the default behaviour would be to display multiple widgets each Static Content widget to the user, based on according to the layers that apply to them.
But what if you only want one banner to be shown? This is where Layer Groups come in.
How It Works
From version 3.94+, you can group layers together so that only the first layer from a group gets applied to a user. In other words, by grouping the Government, Education, and B2C layers together, you could ensure that only one promotional banner image displayed to each user, even if they belonged to all 3 of those customer segments. In a group of layers, only the first relevant layer gets applied, resulting in only one widget being displayed.
