Google Apps Script for 2 Dynamic Dropdowns from 2 separate tables - google-apps-script

Question

I have the following Google Apps onEdit Script which looks up the table in columns A:D in my 'DropDown Lists' sheet. This works for the dropdown in column C of the 'HISOP Training' sheet when the Branch is selected in the dropdown in column A of the same sheet:
//Dynamic Dropdown for HISOP Training
{
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var tablists = 'Dropdown Lists';
var tabValidation = 'HISOP Training';
var ss = spreadsheet.getActiveSheet();
var datass = spreadsheet.getSheetByName(tablists);
var activeCell = ss.getActiveCell();
if (
activeCell.getColumn() == 1 &&
activeCell.getRow() > 1 &&
ss.getSheetName() == tabValidation
) {
activeCell
.offset(0, 2)
.clearContent()
.clearDataValidations();
var base = datass.getRange(2, 1, 1, 5).getValues();
var baseIndex = base[0].indexOf(activeCell.getValue()) + 1;
Logger.log(baseIndex);
if (baseIndex != 0) {
//Dynamic dropdown for 'Employee'
var validationRange = datass.getRange(6, baseIndex, 150);
var validationRule = SpreadsheetApp.newDataValidation().requireValueInRange(validationRange).build();
activeCell.offset(0, 2).setDataValidation(validationRule);
}
}
if (ss.getSheetName() == tabValidation) {
var lock = LockService.getScriptLock();
if (lock.tryLock(0)) {
autoid_(ss);
lock.releaseLock();
}
}
}
I now also want the dropdown in column D of the 'HISOP Training' sheet to select from the range BO:BR of the 'Dropdown List' sheet when the Branch in Column A of the 'HISOP Training' sheet is selected but I don't know how to write the script for this.
This is an image of my 'HISOP Training' sheet:

I would really appreciate some help with this.
Final answer:
function myOnEdit(e){
var sheet = SpreadsheetApp.getActive().getSheetByName('HISOP Training');
var sheet2 = SpreadsheetApp.getActive().getSheetByName('Dropdown Lists');
var value = e.value;
var col = e.range.getColumn();
var row = e.range.getRow();
if(col==1 && e.range.getValue()=='New York' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
// 2 is for dropdown D
var dropdownData = sheet2.getRange("A6:A150").getValues().flat();
var dropdownData2 = sheet2.getRange("BO4:BO150").getValues().flat();
var allowDropdown = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+3).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule2);
}
if(col==1 && e.range.getValue()=='London' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
var dropdownData = sheet2.getRange("B6:B150").getValues().flat();
var dropdownData2 = sheet2.getRange("BP4:BP150").getValues().flat();
var allowDropdown = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+3).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule2);
}
if(col==1 && e.range.getValue()=='Paris' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
var dropdownData = sheet2.getRange("C6:C150").getValues().flat();
var dropdownData2 = sheet2.getRange("BQ4:BQ150").getValues().flat();
var allowDropdown = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+3).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule2);
}
if(col==1 && e.range.getValue()=='Tokyo' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
var dropdownData = sheet2.getRange("D6:D150").getValues().flat();
var dropdownData2 = sheet2.getRange("BR4:BR150").getValues().flat();

Solution
From my interpretation of your question you want to be able to only select a dropdrown of values in columns C and D only if a specific value is selected in column A. To provide a solution to this question instead of providing a specific answer to your sheet case I have provided a general solution abstracting the question so that others with similar questions can easily interpolate the answer and use it as well. You will just need to adapt this answer to you case.
To achieve this I have set up a conditional on an onEdit function to catch changes in the sheet and if this conditional is met (in your case if the branch in column A is selected) then you will be able to select from C and D dropdowns. The following code that solves the issue has self explanatory comments:
function onEdit(e) {
var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
// Get the value of the cell changed
var value = e.value;
// Get col and row of the cell changed to make sure it was in col A
var col = e.range.getColumn();
var row = e.range.getRow();
// If col A. Here you could also add another condition to the if for instance if the value on col A
// is equal to whatever value you want to select in the dropdown in A, then execute this
if(col==1 && e.range.getValue()=='VALUE 1'){
// Get the data for the range of the dropdown. Here you choose if you want to insert dropdowns for C and D
var dropdownData = sheet.getRange("C1:C5").getValues().flat();
// Get the cell we will let the dropdown go (clear all previous content and data validations)
// In your case these you be the columns D and
var allowDropdown = sheet.getRange(row, col+1).clearDataValidations().clearContent();
// Create rules for the respective dropdowns of C and D (in this case is just one rule because I am
// just using a single dropdown to exemplify how to do this
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
// Set the data validation
allowDropdown.setDataValidation(rule);
}
// SECOND RANGE. REPEAT FOR THE REST IF WE HAVE MORE SUB RANGES
if(col==1 && e.range.getValue()=='VALUE 2'){
var dropdownData = sheet.getRange("D1:D5").getValues().flat();
var allowDropdown = sheet.getRange(row, col+1).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
allowDropdown.setDataValidation(rule);
}
}
And this is how this example would look like in the sheet:
As you seem to have difficulties understanding, I have adjusted the general case scenario to your specific situation and I have done for you both the right dropdowns for columns C and D. These are as follow:
function onEdit(e) {
var sheet = SpreadsheetApp.getActive().getSheetByName('HISOP Training');
var sheet2 = SpreadsheetApp.getActive().getSheetByName('Dropdown Lists');
var value = e.value;
var col = e.range.getColumn();
var row = e.range.getRow();
if(col==1 && e.range.getValue()=='New York' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
// 2 is for dropdown C
var dropdownData = sheet2.getRange("BO4:BO49").getValues().flat();
var dropdownData2 = sheet2.getRange("Z2:Z4").getValues().flat();
var allowDropdown = sheet.getRange(row, col+3).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule);
}
if(col==1 && e.range.getValue()=='London' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
var dropdownData = sheet.getRange("BP4:BP45").getValues().flat();
var dropdownData2 = sheet2.getRange("AA2:AA3").getValues().flat();
var allowDropdown = sheet.getRange(row, col+1).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule);
}
if(col==1 && e.range.getValue()=='Paris' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
var dropdownData = sheet.getRange("BQ4:BQ43").getValues().flat();
var dropdownData2 = sheet2.getRange("AB2:AB4").getValues().flat();
var allowDropdown = sheet.getRange(row, col+1).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule);
}
if(col==1 && e.range.getValue()=='Tokyo' && row>2 && e.range.getSheet().getName()=='HISOP Training'){
var dropdownData = sheet.getRange("BR4:BR33").getValues().flat();
var dropdownData2 = sheet2.getRange("AC2:AC3").getValues().flat();
var allowDropdown = sheet.getRange(row, col+1).clearDataValidations().clearContent();
var allowDropdown2 = sheet.getRange(row, col+2).clearDataValidations().clearContent();
var rule = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData, true).build();
var rule2 = SpreadsheetApp.newDataValidation().requireValueInList(dropdownData2, true).build();
allowDropdown.setDataValidation(rule);
allowDropdown2.setDataValidation(rule);
}
}
I hope this has helped you. Let me know if you need anything else or if you did not understood something. :)
