Hi everybody,

I am trying to setup my personal ELog, defining attributes and stuff like that. I just tried to make some nested commands but I really could not achieve that. 

The idea is something like this:

Attributes = Author

Options Author = Tizio{1}, Caio{2}, Sempronio{3}

{1} Attributes = Author, Project

{1} Options Project = Proj1{a}, Proj2{b}, Proj3{c}

{a} Attributes = Author, Project, Year

{a} Options Year = 2017, 2019

Anyway, when I select Proj1 nothing really happens. So, is there any way to set up nested commands like in the reported example?

Many thanks in advance!

P.S. Is there any documentation in which are reported all the possible commands that can be used?
