I can’t find Apache gui config in yast. Documentation says that it should be there but it’s definately not there. Apache2 is installed, it’s working. No, editing files is not a solution for me. It should be and I want that.
Found solution myself. Documentation is bad.

I need yast2-http-server installed. Documentation say nothing about that.
I assume that when you install the LAMP pattern, it will be installed. Is that not the case?
While I don’t doubt that documentation can always be improved, I would encourage users to participate by contributing, or at least report/suggest where necessary. That can be done via the following channels…

BTW, to search which yast2 modules are available and which are already installed…
zypper se -a yast2
For a list of modules available in you current environment you can also do
sudo yast2 -l
It’s on my machine by default. Name is yast2 http-server. 
The OP is aware of the package (they mention it in the second reply), but they were complaining that it wasn’t obvious about what was needed from reading the documentation.
I’m not sure what triggers it to be installed. The lamp_server pattern doesn’t appear to…
