Grid presentation

Hi all,
I have records structured like that:

id, isPresent, txt1,txt2,txt3,txt4

I filter my grid on isPresent=1

Depending of the situation, txt2,txt3 and txt4 can be empty.

My problem is that the grid (in diapositive mode, in a block with one record by row) display space for the empty fields. I would like, in case a field is empty, to don’t generate a place in the grid (that waste space and it is not esthetic).
Is this possible ? Does someone have an idea ?

Thanks

Sylvain
