There is for example; combobox A where there are say 2 items. If Item #1
is
selected, then Combobox B has say 10 items to choose from. If item #2 is
selected from combobox A, then combobox B has 7 items to choose from.

Thanks,
Richard

How does the user make a choice?

When you say a list will appear - you mean a listbox?

The more detail you can describe, the more focused the answer will be.
