conditional block

[rslemer]

is there any solution to this demand?

I say, display or not a block of fields according to another specific field

Yes, you can do that with this extension:

http://corebos.org/documentation/doku.ph...bcolorizer

which will also permit you to color different cells and rows.

and also with the "Field_Dependencies" branch available on github. The code in that branch needs my validation but I haven't been able to get to it yet.
