如何在django表单中添加可搜索的选择字段

from django import forms

class MyForm(forms.Form):
    my_field = forms.ChoiceField(widget=forms.Select(attrs={'class': 'select2'}))

{% load static %}

<link href="{% static 'select2/select2.min.css' %}" rel="stylesheet">
<script src="{% static 'select2/select2.min.js' %}"></script>

<form>
    {{ form.my_field }}
</form>

<script>
    $(document).ready(function() {
        $('.select2').select2();
    });
</script>

<form>
    {{ form.my_field }}
</form>

<script>
    $(document).ready(function() {
        $('.select2').select2({
            ajax: {
                url: '/path/to/remote/data',
                dataType: 'json',
                processResults: function(data) {
                    return {
                        results: data
                    };
                }
            }
        });
    });
</script>

from django.http import JsonResponse

def get_remote_data(request):
    # 从数据库中获取选项数据
    data = [
        {'id': 1, 'text': 'Option 1'},
        {'id': 2, 'text': 'Option 2'},
        {'id': 3, 'text': 'Option 3'},
    ]
    return JsonResponse(data, safe=False)
