In iCloud Numbers how do I set up a popup menu in an entire column
I have a database using iCloud Numbers. The table is for my tax deductions for 2014. In one column I have Doctors/Dentists/etc. Instead of typing that title each time I create a new entry in that column, how can I set a popup menu like I can in Excel and choose Doctors/Dentists/etc?
