Django Crispy Forms结合Tailwind CSS 4.0表单出现多余向下箭头问题

更新 #

这是crispy-tailwind的已知问题，临时解决方案是在你的CSS中添加以下规则，隐藏自动插入的箭头元素：

select ~ .pointer-events-none {
    display: none !important;
}

期待该Bug能在crispy-forms的后续版本中被修复。

问题描述 #

在Django项目中配置crispy-tailwind模板包后，使用crispy-forms在concert_form.html模板中渲染表单时，某个字段（如venue下拉框）后方会出现一个大型向下箭头。注释掉crispy-forms的渲染代码后，表单显示正常。通过浏览器开发者工具确认：启用crispy-forms时，页面会自动插入一个包含SVG箭头的div元素；禁用时该元素不存在。目前仅使用tailwind --watch生成的CSS，希望找到控制crispy-forms避免此问题的方法。

当前使用的技术版本 #

• Django 5.2.1
• Tailwind CSS 4.0
• crispy-tailwind 1.0.3
• django-crispy-forms 2.4

已尝试的方法 #

• 移除crispy-forms：表单渲染正常，但丢失了crispy-forms提供的样式
• 开发者工具排查：确认箭头元素仅在启用crispy-forms时生成
