Variations

You can use variations to assign different content to clients or client groups. To do this, create variations and assign one or more clients to them. You can then make the assignment to the variations in the element properties. Conditional properties can also be based on variations. 

Configurations

Create configurations if you require different client settings for clients or client groups. First you need to create variations. Then add a new configuration for each variation of client settings that you require. If configurations exist, you can select them in the client settings in the top line to customize them.
