Goal
I am trying to add a Bootstap 4 Popover into a field that uses the ModelSelect2Widget
So when the field is hovered / focussed the popover will be displayed.

Problem
The popovers for select2 fields are not shown/triggered. (but visible in the html).
by removing {{ form.media.js }} they will be shown, but then i cant use the select2 features.

(Other fields e.g. CharField do work with this popover.)

Code Snippet

forms.py

from django import forms
from django_select2 import forms as s2forms

class UserPicker(s2forms.ModelSelect2Widget):
    search_fields = [
        "first_name__icontains",
        "last_name__icontains",
    ]

class MyForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields["user"].widget.attrs.update({
            'data-html': 'true',
            'title': 'my title',
            'data-toggle': 'popover',
            'data-trigger': 'focus hover',
            'data-content': '<h1>Hello World</h1>',
            'data-placement': 'right',
        })

    class Meta:
        model = MyModel
        fields = ("user",  )
        widgets = {
            "user": UserPicker(),
        }

html template:

{% load static %}
{% load crispy_forms_tags %}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <!-- Select2 CSS -->
    <link rel="stylesheet" href="{% static 'select2/css/select2.css' %}">

    <!-- Add jQuery (required for Bootstrap's JavaScript plugins) -->

</head>
<body>
    {{ form|crispy }}
    {{ form.media.js }}
    
    <style>
      .select2-container {
          width: 100% !important;
      }
      .select2-selection {
          height: 40px !important;
          line-height: 40px !important;
      }
    </style>

    <!-- Initialize the popover with JavaScript -->
    <script>
        $(document).ready(function(){
            $('[data-toggle="popover"]').popover();
        });
    </script>
</body>
</html>

Hi @urzbs,

Thanks for reaching out. Honestly, I haven't used Bootstrap in a whee bit. However, I presume your issues comes from Select2 injecting custom DOM and hiding the original select-tag. However, you can bind your toggle to the DOM that's been injected. You will have more success though asking the Select2 community for help. This package is merely the Django integration. The JS community is more experienced with those issues.

I hope my direction helps.

Cheers!
Joe
