I want to create an option for the user to choose between lessons. There are more than 4 lessons that are in the picture.

For every lesson there are 3 options:

1. The lesson is full - the user can't register to this lesson
2. The user can register to this lesson
3. The user already registered to this lesson.

I think how can I do this? Make every option block in different color? Where to put the button to register (where the YES NO buttons are now?)

Or make the blocks clickable to register?
