Hi Nikesh, I apologize for the delay over the end-of-year holiday period.
If I understand your question correctly, you'd like to dynamically change what is shown to users based on the value of a particular user attribute.
That is possible through the use of Targeting Attributes, where you'd show different variations based on different attributes.
You would need to define these attributes in the GrowthBook dashboard, and use the Visual Editor to define the variations.
