hello my problem set before you
I have 4 combobox, where only the first has four items such as A, B, C, D
the other 3 have not combobox item, are empty.
if I choose the first combobox un'item (example A), automatic I need the other 3 in the second combobox item that is (B, C, D).
if I choose an item in the second combobox (say B) in the third combobox I have only
two items ie (C, D).
If I choose the third one of the two remaining items, automatic I populate the combobox with the latest fourth item.
Another thing is, if the replacement option in the first combox (example I choose the third item C) should clear all the options I had chosen for the other combobox
how do I proceed?
