如何在django中创建下拉菜单

from django.db import models

class Choice(models.Model):
    option = models.CharField(max_length=100)

from django import forms
from .models import Choice

class ChoiceForm(forms.Form):
    choice = forms.ModelChoiceField(queryset=Choice.objects.all())

from django.shortcuts import render
from .forms import ChoiceForm

def create_dropdown(request):
    if request.method == 'POST':
        form = ChoiceForm(request.POST)
        if form.is_valid():
            form.save()
            # 处理表单提交成功后的逻辑
    else:
        form = ChoiceForm()
    return render(request, 'create_dropdown.html', {'form': form})

<!-- create_dropdown.html -->
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">提交</button>
</form>
