Populate Multiselect field value in Power Pages (Multistep Forms)

Hi Team,

I have a requirement to populate values from a multiselect option to another multiselect option in Power Pages (Dataverse). Both have the same values and reference the same option set.

if (region) {
// Convert the comma-separated string into an array of strings
var selectedValues = region.split(',');

// Set the multiselect dropdown using the array
$('#new_region').val(selectedValues);

// IMPORTANT: Trigger the change event to update the UI
$('#new_region').trigger('change');
}

The code executes without any issues, but on the Power Pages portal multistep form, the values are not getting populated. Has anyone else encountered this issue?

(I am not sure if you are saying the obtaining & setting of values or picking up the change on the first dropdown is the issue)

For how to obtain & set multiselect values please refer to the following link from Oliver:
