Like the earlier days in Joomla 3, the module positions comes with the template.
I choose "left" or "right" for perfect sidebar positions, but nothing happends.
Footer, top or bottom works, content-top also not......

Do I miss something?

Look here:

Thanks for the hint. This shows for me a 3 Joomla framework.
I'm affraid not to see the connection between the list of possible module positions when creating a new module and most of this positions does not work. Why I have to fumble around with this astroid-stuff - I was for many years very satisfied with the simple but nice joomlaplate-templates and used many of them a lot.

It is the same like Joomla 4:



And you can see, create or delete modulpositions in the layoutmanager:

Hello,
you can create module positions in Joomla and then assign these positions in Astroid.

Many thanks, but this does not work for me!
laborious fumble without any advantage with this additional astroid.step for module position.

Are there still joomlaplate-templates for J4 without this?
