Use Loop operators in a sequence diagram with RSA

Question

RSA I installed on my machine. I would use a sequence diagram .. after New -> Diagram -> Sequence Diagram insert the LifeLine

I would like the Loop combinated Fragment and a Fragment Alt combinated but which are not included in the Panel. How do I restore them?

Thanks to all who help me

Answer 1

I think you just have to reset your perspective.

Answer 2

Next to "Option Combined Fragment" you should see a little arrow. Click on it it'll drop down all the other combined fragments available.
