special questions

Hi. special questions.

questions 1:

Is it possible if, as in my case, field 1 is active and field 4 is selected, that you click on field 2? Without having to deselect field 4?

questions 2:

It would be perfect if fields 1, 2 and 3 always remain clickable and only the lower fields vary. Is the ?

So field 1,2,3 remain visible
If I click on field 1, you only see fields 4 and 5
-
If I click on field 2, you only see fields 6 and 7
-
If I click on field 3, you only see fields 8 and 9
-

But if I then activated field 3 and 9, I can still go to field 2 and then field 6 and 7 are shown to me

thank you for help
