将鼠标悬停在 组合框中的项目上时，是否有任何方法可以更改光标?我假设做 option { cursor: pointer;} 在 CSS 中可以工作，但似乎不行.
Is there any way to change the cursor when hovering over an item in a <select> combobox? I assumed that doing option { cursor: pointer; } in CSS would work, but it doesn't seem to.

制作自己的下拉菜单
标签是由操作系统呈现的，而不是浏览器，因此您无法设置它们的样式.
Make your own dropdown
<option> tags are rendered by the operating system, not the browser, so you can't style them.

Instead, make your own dropdown that you can fully control or use a 3rd-party plugin, for example Bootstrap's Dropdown.

Some elements simply can't be styled using CSS. These include all advanced user interface widgets such as range, color, or date controls as well as all the dropdown widgets, including
<select>,<option>,<optgroup>and<datalist>elements. The file picker widget is also known not to be stylable at all. The new<progress>and<meter>elements also fall in this category.
