Infinite Dependent Drop Down Lists in в Google Sheets (Part 2)

This article is a continuation of Infinite Dependent Dropdowns in Google Sheets.

Changes and additions to the code are described here, namely:

Automatic creation of sheets Nome Data_2;
Automatic addition of all formulas on sheet Nome;
When editing the row of dependent (linked lists) created earlier, the values and formulas to the right of the edited cell are automatically deleted.

function onEdit(e) {

  var row = e.range.getRow();
  var col = e.range.getColumn();
  var list_name = e.source.getActiveSheet().getName();
  var name = e.value;
  var oldName = e.oldValue;
  var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Home');
  var mask = JSON.stringify(sh.getRange(row, 1, 1, col).getValues()[0]);
  var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Home');
  var colMax = sh.getLastColumn();
  
  if(list_name === "Home" && name !== oldName && col < colMax) {
    fillColumn(row, col, mask);
  }
}

function onOpen() {
  var ui = SpreadsheetApp.getUi();
  // Or DocumentApp or FormApp.
  ui.createMenu('Custom Menu')
      .addItem('Create sheets', 'createSheets')
      .addToUi();
}


function fillColumn(row, col, mask) {

// clear dataVal and Value
  var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Home');
  var colMax = sh.getLastColumn();
  sh.getRange(row, col + 1, 1, colMax).clearDataValidations().clearContent();

// find date
  var sd = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Data");
  var arrData = sd.getDataRange().getValues();
  var arrData_2 = [];
  arrData_2.push(arrData[0]);
  
  var iMax = arrData.length - 1;
  for(var i=1; i<=iMax; i++) {
    if(JSON.stringify(arrData[i].slice(0, col)) == mask) {
      arrData_2.push(arrData[i]);
    }
  }
   
// clear Data_2
  var sd_2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Data_2");
  sd_2.getDataRange().clearContent();

// insert data
  sd_2.getRange(1, 1, arrData_2.length, arrData_2[0].length).setValues(arrData_2);
  
// add dataVal
  col++;
  var list = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K'];
  var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Home');
  sh.getRange(row, col).setDataValidation(SpreadsheetApp.newDataValidation()
  .setAllowInvalid(false)
  .requireValueInRange(sh.getRange('Data_2!$' + list[col - 1] + '$2:$' + list[col - 1] + '$1000'), true)
  .build());
}

function createSheets() {

// is exist Home?
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sd = ss.getSheetByName('Data')
  
// create if not exist
  if(!ss.getSheetByName('Home')) {
    ss.insertSheet('Home', 0);
// create Data Val
    var sh = ss.getSheetByName('Home');
    sh.getRange('Home!A2:A20').setDataValidation(SpreadsheetApp.newDataValidation()
      .setAllowInvalid(false)
      .requireValueInRange(sh.getRange('Data!$A$2:$A'), true)
      .build());
    sh.getRange(1, 1, 1, 10).setValues(sd.getRange(1, 1, 1, 10).getValues()).setFontWeight('bold');

  };

// is exist Data_2?
  if(!ss.getSheetByName('Data_2')) {
   
// create if not exist
    var k = ss.getNumSheets();
    ss.insertSheet('Data_2', k + 1);
    var sd_2 = ss.getSheetByName('Data_2');
    sd_2.getRange(1, 1, 1, 10).setValues(sd.getRange(1, 1, 1, 10).getValues()).setFontWeight('bold');
  };
}

Now, in this version of the program, it is possible to automatically create all the sheets of the file necessary for the script to work (including data formatting and validation) by pressing just one(!) button from the user menu.

All you need for this:
