答案 0 :(得分：0)
<select>和<option>标签 <select>和<option>标签很难自定义，任何一种适用于一个浏览器的标签都不适用于其他标签。
<select>，使用<select>和<details> <summary> ✱
<select> <details>＆<summary> <option>，使用<option>和<input type='radio'> <label> ✱
<option> <input type='radio'>＆<label> ✱伪<select>和伪<option>标签的外观和行为将与标准<select>和{{1} }标签。更重要的是，它可以存储和处理<option>，并且可以将其注册到value事件中。
