select2 - how preselecting multiple options that receive data from an AJAX remote source

I have a modal that has two 'behaviors', one to create new record and another to edit existing record, depending on which button is clicked (new / edit).

When you click edit, the record data (users table) is loaded 'along' with the child records (permissions table).

During modal loading, the select2 is initialized:

let $select2user    = $(".select2user");



$select2user.select2({

    ajax: {

        url: 'getUsersWithPermissions.php',

        type: "GET",

        dataType: 'json',

        data: function (params) {

            return {

                search: params.term,

                page: params.page || 1

            };

        },

        processResults: function (data) {

            data.page = data.page || 1;

            return {

                results: data.items.map(function (item) {

                    return {

                        id: item.id,

                        text: item.name

                    };

                })

            }

        },

        cache: true,

        delay: 250

    },

    multiple: true

});

Everything works fine, except when I click edit a record.

The inputs form (modal) are filled in correctly with the registration data, however, I cannot pre-select multiple options from child records (permissions table).

I tried to use 'append', but it ends up generating duplicate options.

$.each( value, function( permissions, permission ) {

  console.log(permission['name']); // ok

  let newOption = new Option(permission['name'], permission['id'], false, true);

  $select2user.append(newOption);

});

$select2user.trigger('change');

$(document).ready(function() {

  var _selectedValues = ;

  _selectedValues.push('1');

  _selectedValues.push('5');

  _selectedValues.push('8');

  $("#selectlist").select2().val(_selectedValues).trigger("change");

You can try like this, to set the values in select2.

var _selectedValues = ;

_selectedValues.push('1');

_selectedValues.push('2');

_selectedValues.push('3');

$("#selectlist").select2().val(_selectedValues).trigger("change");

Thanks for the collaboration, however, your suggestion works for 'static' options, but unfortunately, it does not work for 'dynamically' loaded (remote source ajax) options.

As you mentioned, you are getting duplicate options (by append), instead of append, add the id to array and execute this code in ajax success block,
