Normally that icon indicates, where the user would have to click to start the search. Why do you want to use that icon for every option?
通常,该图标指示用户必须单击才能开始搜索的位置。为什么每个选项都要使用该图标?

I cannot see your code in order to help you fix your issue according to your need, but you are close to where you needed to be, which is to utilize the renderOption
props for <Autocomplete>
component.
我看不到您的代码是为了帮助您根据需要修复问题,但您已经接近了所需的位置,即使用
组件的renderOption道具。
In this case, what you want to do is actually this
在这种情况下,您要做的实际上是
<Autocomplete
renderOption={(props, option) => (
<li {...props}>
<SearchIcon />
{option.label}
</li>
)}
// ... and rest of the props
/>

Thanks for your help! But my options structure is [option1, option2], it doesn't have a label. Then what should I put in "{option.label}" ?
谢谢你的帮忙!但我的期权结构是[option1,option2],它没有标签。那我应该在“{option.bel}”里填什么呢?
In that case, just option
will suffice, because MUI automatically knows what is passed in for the autocomplete. I have updated the CodeSandbox demo that matches more to your scenario so you can refer to :)
在这种情况下,只要选项就足够了,因为MUI自动知道为自动完成传入了什么。我已经更新了与您的场景更匹配的CodeSandbox演示,因此您可以参考:)
