Google Sheets script to allow multi-select in cells with data-validation (adapted from https://www.youtube.com/watch?v=dm4z9l26O0I)
<div style="font-family: sans-serif;">
<? var data = valid(); ?>
<form id="form" name="form">
<? if(Object.prototype.toString.call(data) === '[object Array]') { ?>
<? for (var i = 0; i < data.length; i++) { ?>
<? for (var j = 0; j < data[i].length; j++) { ?>
<input type="checkbox" id="ch<?= '' + i + j ?>" name="ch<?= '' + i + j ?>" value="<?= data[i][j] ?>"><?= data[i][j] ?><br>
<? } ?>
<? } ?>
<? } else { ?>
<p>This cell has no <a href="https://support.google.com/drive/answer/139705?hl=en">Data validation</a>.</p>
<? } ?>
<input type="button" value="Select" onclick="google.script.run.fillCell(this.parentNode)" />
<input type="button" value="Refresh validation" onclick="google.script.run.showDialog()" />
</form>
</div>
function onOpen(e) {
SpreadsheetApp.getUi()
.createMenu('Scripts')
.addItem('Multi-select for this cell...', 'showDialog')
.addToUi();
}
function showDialog() {
var html = HtmlService.createTemplateFromFile('dialog').evaluate();
SpreadsheetApp.getUi()
.showSidebar(html);
}
var valid = function(){
try{
return SpreadsheetApp.getActiveRange().getDataValidation().getCriteriaValues()[0].getValues();
}catch(e){
return null
}

function fillCell(e){
var s = [];
for(var i in e){
if(i.substr(0, 2) == 'ch') s.push(e[i]);

Everything works UNTIL I click on "select" and nothing happens :-( I am so grateful for this solution, I need to make this work... I would really appreciate any help you can give!

I'm having this same problem. Select just does nothing when it's suppose to set the values.

@joshuajohnsont and @MeesLorch. I found this resolution on a different page and it fixed the issue for me!

  1. Open the Script Editor (Tools > Script Editor).
  2. Project Settings (left menu).
  3. Uncheck 'Enable Chrome V8 runtime'

Hope that helps! :)

Is it possible to modify this script to give the user a option of entering free Text ???????
