First you must find the source of your list. It's usually somewhere in the
same spreadsheet that contains the drop-down combo.

Then, the easy way is to insert a cell anywhere between the first and the
last cells of that list, or to *cut* the last cell and paste it one or more
cells down.

OR, you may edit the reference of the source for your list. Drop-down cells
may be combo-boxes or only a data validation. Try to discover what type it
is, and then edit its properties (if a combo-box) or the validation source.

Is it possible to add another item on an existing drop-down list?
If yes, please give me some information on how to do it.
Thank you!
