Multiline options for Material UI autocomplete

Question

I'm trying to make an autocomplete where each option has firstName and lastName of a user on the first line and their id on the second.

Here is what I've tried

<Autocomplete
        freeSolo
        disableClearable
        options={users}
        getOptionLabel={(option) => option.firstName + " " + option.lastName}
        renderOption={(option) => {
          return (
            <>
              <div>
                {option.firstName} {option.lastName}
              </div>
              <div>{option.id}</div>
            </>
          );
        }}
        renderInput={(params) => (
          <TextField
            {...params}
            label="Username or ID"
            // margin="normal"
            variant="outlined"
            value={name}
            onChange={handleChange}
            className={classes.input}
            InputProps={{
              ...params.InputProps,
              type: "search",
            }}
          />
        )}
      />

I'm returning a component from renderOption but it does not pay attending to <div> or <br/> tags. It simply puts everything next to each other

Just use proper div to display on next line. Single Outer div and one nested div to show the id on next line.

renderOption={(option) => {
      return (
        <>
          <div>
            {option.title} {option.title}
            <div>
              {option.title}
            </div>
          </div>
        </>
      );
    }}
