Delete and add columns in google sheet - google-apps-script

Question

I am using the below code to create the validations in google sheet (contributed by Cooper), what this script does is it automatically check the applicable headers and create the dropdown with values and hide the columns which are not applicable.
I am trying to solve here is:
The script checks the applicable headers related to the Product Selection
It creates the dropdown with validation values
Instead of hiding the not applicable columns, It removes them from the sheet
I am a beginner to google script and tried using the deletecolumn function but unable to get it work.
Please help me out here.
function loadObjectsAndCreateProductDropDown() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Sheet0');
const psh = ss.getSheetByName('Sheet1');
const [ph, ...prds] = sh.getRange(1, 1, 10, 6).getValues().filter(r => r[0]);
const [ch, ...chcs] = sh.getRange(11, 1, 10, 10).getValues().filter(r => r.join());
let pidx = {};
ph.forEach((h, i) => { pidx[h] = i });
let prd = { pA: [] };
prds.forEach(r => {
if (!prd.hasOwnProperty(r[0])) {
prd[r[0]] = { type: r[pidx['Type']], size: r[pidx['Size']], color: r[pidx['Color']], material: r[pidx['Material']], length: r[pidx['Length']] };
prd.pA.push(r[0]);
}
});
let cidx = {};
let chc = {};
ch.forEach((h, i) => { cidx[h] = i; chc[h] = [] });
chcs.forEach(r => {
r.forEach((c, i) => {
if (c && c.length > 0) chc[ch[i]].push(c)
})
})
const ps = PropertiesService.getScriptProperties();
ps.setProperty('product_matrix', JSON.stringify(prd));
ps.setProperty('product_choices', JSON.stringify(chc));
Logger.log(ps.getProperty('product_matrix'));
Logger.log(ps.getProperty('product_choices'));
psh.getRange('A2').setDataValidation(SpreadsheetApp.newDataValidation().requireValueInList(prd.pA).build());
}
//I chose to use an installable dropdown. I'm not sure if it's needed. Its up to you.
function onMyEdit(e) {
//e.source.toast('entry')
const sh = e.range.getSheet();
if (sh.getName() == 'Sheet1' && e.range.columnStart == 1 && e.range.rowStart == 2 && e.value) {
//e.source.toast('flag1');
sh.getRange('C2:G2').clearDataValidations();
let ps = PropertiesService.getScriptProperties();
let prodObj = JSON.parse(ps.getProperty('product_matrix'));//recovering objects from PropertiesService
let choiObj = JSON.parse(ps.getProperty('product_choices'));
let hA = sh.getRange(1, 1, 1, sh.getLastColumn()).getDisplayValues().flat();
let col = {};
hA.forEach((h, i) => { col[h.toLowerCase()] = i + 1 });
["type", "size", "color", "material", "length"].forEach(c => {
if (choiObj[prodObj[e.value][c]]) {
sh.getRange(e.range.rowStart, col[c]).setDataValidation(SpreadsheetApp.newDataValidation().requireValueInList(choiObj[prodObj[e.value][c]]).build()).offset(-1,0).setFontColor('#000000');
sh.showColumns(col[c])
} else {
sh.getRange(e.range.rowStart, col[c]).offset(-1,0).setFontColor('#ffffff');
sh.hideColumns(col[c]);
}
})
}
}

Suggestion
This may not be the cleanest code but you may try this implementation below. Instead of removing columns, it will clear the Sheet1 headers and their corresponding drop-downs on every new selection on the A2 drop-down.
NOTE: Since your sample data will increase in size overtime, this setup will need you to put the data into a separate sheet tab for a cleaner setup, such as this sample below:
Data1 sheet tab:
Data2 sheet tab:
UPDATED
Sample Script
var sh = SpreadsheetApp.getActiveSpreadsheet();
var selection = sh.getSheetByName("Sheet1").getRange("A2").getValue(); //Get the selection on the dropdowm on cell A2
var data1 = sh.getSheetByName("Data1").getDataRange().getDisplayValues();
var data2 = sh.getSheetByName("Data2").getDataRange().getDisplayValues();
function addHeaders(sheet, values) { //Adds the headers from Column C and beyond
var startCol = 3; //Column C
var endCol = startCol + values.length;
values.forEach(x => {
if(startCol <= endCol){
if(checkHeaderIfYesOrNo(x) == true)return;
sheet.getRange(1,startCol).setValue(x);
startCol += 1;
}
});
}
function onEdit(e) {
if(e.range.getA1Notation() != "A2")return;//Make sure to run onEdit function ONLY when cell A2 is edited/selected
var headers = [];
var headerValues = [];
var temp = [];
var counter = 0;
clean();
data1 = fixDuplicates();
//find selection name on data1
for(var x = 0; x< data1.length; x++){
var name = data1[x][0];
if(name == selection){
///get the headers & their values
data1[x].forEach(res => {
if(res != "" & res != selection){
var index1 = data1[x].indexOf(res);
var index2 = data2[0].indexOf(res);
headers.push([data1[0][index1]]);
for(var y=0; y< data2.length; y++){
if(data2[y][index2] != "" && data2[y][index2] != res){
temp.push("**"+res+"**"+data2[y][index2]); //place raw header data to a temporary variable
}
}
//Set the drop-down data of each headers
temp.forEach(raw => { //clean the temp array
if(raw.includes(res)){
var regex = /\*\*([^*]*(?:\*(?!\*)[^*]*)*)\*\*/g;
headerValues.push(raw.replace(regex, ""))
}
});
//Logger.log("Data of the \""+res+"\" header:\n"+headerValues);
//set data validation per header
counter += 1;
if(res.toLowerCase().includes("no"))return; //skip creating data validation for "No" header

}
return data1New;
}

Logger.log(h +" contains Yes");
return null;
}else if(data1[x][data1[0].indexOf(h.toString())].toLowerCase().includes("no")){
Logger.log(h+" header will not be added as it has \"No\" value");
