The data validation dropdown is limited to 8 rows, and can't be changed.

If you can use macros, there's a sample file here that provides a
combobox from which you can select one of the values. In a combobox, you
can set the number of rows in the dropdown list:

Under 'Data Validation', look for 'Data Validation Combobox'

Data...Validation...List allows a drop down list from a cell. The default
appears to be about 7 items from the list. Is there a way to increase the
number of items from the list?
