Missing Modul Dependency alkacon.mercury.extension.section_ext

[ismailagac]

Hi,

I am trying to get to know the new Opencms Milestone 14 to build own Template variant. Therefore I am trying to install the documentation Modul which is not working because there is a modul named "alkacon.mercury.extension.section_ext" missing.
I would like to see the concept of element override and other features where there is not really example in the new Documentation.

I would thank you all if you could tell me please where to get this modul.

Thank you
Sincerely
IA
