Excel 2007 : How to create drop down list but options reducing after every seclection?

Hi,

Is it possible to do a drop down list that allow user to select pre-defined selections but everytime when a selection is chosen, the list reduced?

Example,

I have can choose Apple, Orange, Durian and Mango.
The drop down can only select these 4 fruits.

So there are 4 cells in Column A1, A2, A3, A4.
A1 selects Mango and then A2 will only have 3 options to choose. So until the last cell, he can only choose the last fruit left.

A1, A2, A3, A4 are not selecting in descending order thus it could be A3 selecting first, then A2 and then A4.

I'm using excel 2007. Hope someone can enlighten me. Thanks.
