Setting text color, outline, and padding on Material-ui Autocomplete component

问题

We'd like to change the text color, outline, and padding on a Material-ui Autocomplete component.

The code looks like this:

              <FormControlLabel
                label="Please enter desired service:"
                labelPlacement="start"
                control={
                  <Autocomplete
                    id="services"
                    options={props.serviceTypes}
                    getOptionLabel={option => option.name}
                    className={classes.inputRoot}
                    style={{ width: 400, paddingLeft: 20 }}
                    renderInput={params => (
                      <TextField
                        {...params}
                        label=""
                        className={classes.inputRoot}
                        variant="outlined"
                        fullWidth
                      />
                    )}
                    onChange={setService}
                  />
                }
              />

We are able to change the TextInput color via code like this

                        InputProps={{
                          className: classes.inputColor
                        }}

but applying a style this way impacts the AutoComplete functionality (it loses the autocomplete functionality and behaves like a normal TextField).

We've tried a number of style and className options to no avail.

Appreciate any advice.

回答1:

Here is the approach you tried (which worked as far as styling, but broke the Autocomplete functionality):

renderInput={params => (
    <TextField
       {...params}
       label=""
       InputProps={{
          className: classes.inputColor
       }}
       variant="outlined"
       fullWidth
    />
)}

The above approach causes problems because the Autocomplete component passes InputProps as part of the params passed to TextField so the InputProps passed explicitly will completely replace the InputProps in params.

Instead, you should leverage the inputRoot CSS class for the Autocomplete component:

<Autocomplete classes={{inputRoot: classes.inputRoot}} .../>

Below is a working example that sets the text color and customizes the outline colors.

import React from "react";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";
import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles(theme => ({
  inputRoot: {
    color: "purple",
    "& .MuiOutlinedInput-notchedOutline": {
      borderColor: "green"
    },
    "&:hover .MuiOutlinedInput-notchedOutline": {
      borderColor: "red"
    },
    "&.Mui-focused .MuiOutlinedInput-notchedOutline": {
      borderColor: "purple"
    }
  }
}));

export default function ComboBox() {
  const classes = useStyles();
  return (
    <Autocomplete
      id="combo-box-demo"
      classes={classes}
      options={top100Films}
      getOptionLabel={option => option.title}
      style={{ width: 300 }}
      renderInput={params => {
        return (
          <TextField
            {...params}
            label="Combo box"
            variant="outlined"
            fullWidth
          />
        );
      }}
    />
  );
}

const top100Films = [
  { title: "The Shawshank Redemption", year: 1994 },
  { title: "The Godfather", year: 1972 },
// Plus a bunch more
];
