Check 'Select All' in the Multi-select list box when a radio button is selected

Recommended Posts

Hi @JanineB - you may try this code:

<script type="text/javascript">
document.addEventListener('DataPageReady', function (event) {
var radios = document.getElementsByName("EditRecordFIELDNAME_RADIOBUTTON");

  for(i = 0; i < radios.length; i++) {
        if(radios[i].addEventListener('change', function() {
            if (this.value == 5) {

              var box = document.querySelectorAll("input[id*='EditRecordFIELDNAME_LISTBOX']");

                for (var i=0; i < box.length ;i++){

            else {

               var box= document.querySelectorAll("input[id*='EditRecordFIELDNAME_LISTBOX']");

                 for (var i=0; i < box.length ;i++){




This is for Details Page or Update Form. If you are planning to use it in the Submission Form, it will be InsertRecordFIELDNAME. Kindly change the FIELDNAME as well to the correct name of your field.

This code means that it will first get all values from the radio button and when it is changed, it will check if the value is equal to 5.

If the radio = 5 THEN select the Listbox AND check all options.
If the radio is not equal to 5 THEN it will uncheck all options. 

Hope it helps!
