Can anyone help?

I am using excel 2003 and want to make it easier to enter data into cells.
Is it possible to create different "dropdown lists" for different columns so
that it is quicker to enter data

e.g. if I wanted to enter which fruit I had eaten on a particular day in
column A out of the following: apple, pear, banana, strawberry, grapes, is it
possible to have that list pop up when I click on a cell in column A, so that
I can just click on the appropriate fruit to enter it into a cell.

Thanks

John
