In this sample Google Sheet that you can edit, I'm trying to configure the data validation dropdown menus in B2:B to only display when the adjacent cells in A2:A have data in them. As you can see in my spreadsheet, I have the data validation configured alright, but it inserts dropdown menus all the way down column B, even if there's no data next to it in Column A, and I don't want that.
How can I configure this to where Data Validation dropdown menus only display when there is data in adjacent cells in column A?
Thanks for your help!
You need a script
function onEdit(event){
var s = event.source.getActiveSheet();
var r = event.source.getActiveRange();
if (r.getColumn() == 1 && s.getName() == 'Dropdowns'){
r.offset(0,1).clearContent()
if (r.getValue() == ''){
r.offset(0,1).clearDataValidations();
}
else{
var lists = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Colors');
r.offset(0,1).setDataValidation(SpreadsheetApp.newDataValidation()
.setAllowInvalid(true)
.requireValueInRange(lists.getRange('A2:A'+lists.getLastRow()), true)
.build());
}
}
}
