I currently have a task managing spreadsheet that is organized by approaching deadline (upcoming deadlines appear first on the list in order of when they are due).
I want to create a dropdown menu at the top of the spreadsheet with options "2015, 2014, 2013, etc" so that I can easily see deadlines from past years. Additionally it would be helpful to be able to have another dropdown menu for the month "April, May, June, July, etc" so that it could be even more specific.
Does anyone know how to do this? I know I have seen this done on accounting spreadsheets, but I can't figure it out.
