How can I deal with tom-select and django form?

I found recently tom-select as alternative to Select2 for my forms. It's a great solution who work perfectly !

It works great when I use to create data from a form but when I want to use to edit data it's another problem.

My edition form is in a modal ad this modal is opened by clicking on edit button on an item listing on main page behind.

I use fetch in javascript to get data and to populate my input/select. It works well when I first open my modal ... but if I click on another item to edit next ... no clear data ... and error message in console saying there is allready an instance of tom-select for this input.

My goal is to retrieve data (sometime it's a single select, sometime it's a multiple select) on tom-select with an easy part as I did with Select2.

Here is my form

<div class="modal fade">[...]
<form id="product-form" method="post" action="{% url 'products' %}" class="mt-2">
    {% csrf_token %}
    {% include 'form.html' with form=form %}
    <input type="hidden" name="id_product" id="id_product" value="" />
    <div class="d-flex gap-2">
        <a href="#" type="button" class="btn btn-secondary col-3" data-bs-dismiss="modal">{% trans 'Retour' %}</a>
        <button id="btn-product-modal" type="submit" class="btn btn-success col-9">{% trans 'Créer' %}</button>

Beginning of my EditModal function

function openModalEdit(pk) {
        // Fetch object data using AJAX
            .then(response => response.json())
            .then(data => {
                // Populate modal fields with fetched data
                for (var i = 1; i <= data.entries; i++) {
                    document.getElementById('id_entry_' + i).value = data['entry_' + i];
                    var selectElement = document.getElementById('id_entry_' + i);
                    var selectedValues = data['entry_' + i];
                    if (selectElement.selectize) {
                    var tomSelect = new TomSelect(selectElement, {
                        items: selectedValues
                document.getElementById('id_description').value = data.description;
                document.getElementById('id_price').value = data.price;

In django here is my

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    for category in categories:
        entry_choices = Entry.objects.filter(category=category).values_list('id', 'name')
        field_name = f'entry_{}'
        new_fields[field_name] = forms.ChoiceField(
            widget=forms.Select(attrs={'class': 'select2 form-control', 'placeholder': _(u'Choisissez votre ') + str(}),
    self.fields = new_fields

and my calling forms

if pk:
    obj = get_object_or_404(Product, pk=pk)
    message = _("Produit édité avec succès !")
    obj = None
    message = _("Produit créé avec succès !")

form = ProductEntryForm(instance=obj)

As you can see I try with destroy() but it doesn't work.

I saw something with sync() , cleaCache() ... etc but don't know how to use them

The objective is to finally find a solution which works with django.
I think I'm close to find a solution but I've some difficult since a while :(
