Setting a default value in a sheet

edited 12/09/19 in Smartsheet Basics

Hi Everyone , 

Is there a tip to set a default value in a sheet column ? I know it is possible to do it by a webform , but it is not my concern . 

I have a drop-down list column , with 2 items : "Oui " et " Non " . How can I  manage so that  " Non " value is displayed in the column by default every time a new row is added . 

Thank you .
