Addictive Drums, cómo lograr pegar sucesión de compases

Hello everyone. I guess my question is very basic. I would appreciate any help, I myself am very basic!
In the Beats section of Addictive Drums, there is a list of drum loops. I drag one of them to a midi track and there it is. My question is how to do so that others can be added successively to that piece. One after another, the same or be able to vary from one to another.
Greetings and many thanks for any help. My language is Spanish and my apologies for any error in the use of the language: I use the Google translator.
