I own a handful of spreadsheets with dropdown menus. Sometimes people, who are responsible for filling these spreadsheets with data, accidentally move cell with dropdown menus from one column to adjacent column. This breaks the whole process of gathering data. Can I somehow protect certain cells from moving?
