                google sheets - dropdown conditions - how to check if certain values are selected for a dropdown cell ?
              
          
    In Google Sheets, the dropdown cell store its value as a comma-separated list of string.
To check if a dropdown cell has value "A" and "B" selected, use the following formula :
=IF(REGEXMATCH(D2;"[\s]?A[,]?") * REGEXMATCH(D2;"[\s]?B[,]?");"YES";"NOPE")

The regex matches a string, prefixed by an optional space, and suffixed by an optional comma.
