Add subject section

[ngoctp29121982]

Hello Liviu. I have a proposal to add subject groups to have the teachers divided into different groups. For example: Math, physics, chemistry, biology teacher, he belongs to the Science and History group, Geography, civics belongs to the Social Sciences group... The purpose of dividing into groups is to add Constraints or view the constraints of the group. It's easier for teachers in specialized groups

Hello, ngo,

This is unfortunately difficult now. I added this in the TODO.

Unfortunately, since I did not think of this feature from the start, now it is very complicated. It won't come to realization soon...
