变体道具不适用于材料ui选择组件

Question

我创建了一个包装材料ui select组件的组件。出于某种原因，当我将其传递给样式不适用于组件的“概述”道具时。有什么想法我做错了吗？

export default function FormSelectInput( props ) {
  const classes = FormStyle();

  return (
    <Grid item xs = {props.xs} className = {classes.formItem}>
    <FormControl className = {classes.formControl} variant = "outlined">
    <InputLabel error = {Validation.isEmpty( props.value )}>{props.label}</InputLabel>
    <Select
      variant = 'outlined'
      // className = {props.className}
      label = {props.label}
      required = {props.required}
      fullWidth
      value = {props.value}
      onChange = {props.onChange}
      input = {<Input />}>
        {props.selectInputs.map( (inputName, key) => {
          const inputClass = inputName.replace("-","")
          return <MenuItem key = {key} value = {inputName} className={classes[inputClass]}>{inputName}</MenuItem>
         })}
    </Select>
    </FormControl>
    </Grid>
  )
}
