Is there a way to customize the font size of Material UI Autocomplete?

Question

Is there a way to customize the font size of Material UI Autocomplete?

I'm currently trying to customize the Material UI Autocomplete component with my own CSS. Specifically, I aim to adjust the font size of the input field. Below is my current implementation:

<Autocomplete
  style={{
    width: 200,
    height: 60,
    marginLeft: 15,
  }}
  options={["foo", "bar"]}
  renderInput={(params) => (
    <TextField
      InputProps={{ style: { fontSize: 30 } }}
      {...params}
      margin="normal"
    />
  )}
/>

It appears that the TextField component is being styled correctly, but it seems like its CSS is being overridden by the Autocomplete CSS. Any assistance on this problem would be highly appreciated. Thank you in advance.

Answer №1

If you're looking to experiment with a couple of changes,

Consider swapping the order of these two lines

InputProps={{ style: { fontSize: 30 } }}
{...params}

to achieve this new structure:

{...params}
InputProps={{ style: { fontSize: 30 } }}

This adjustment is necessary because the second {...params} takes precedence over the InputProps.

To modify the CSS for the Inputprops, you can utilize the !important declaration like so:

InputProps={{ style: { fontSize: `30 !important` } }}

To ensure the autocomplete options are displayed, make sure to include the spreader params.InputProps within InputProps:

InputProps={{ ...params.InputProps, style: { fontSize: `30 !important` } }}

If you're still on the hunt for a solution, here's how you can properly implement CSS properties on the input element in accordance with the Autocomplete API. By using this approach, you gain the ability to assign classes to the underlying elements of the autocomplete component.

<Autocomplete 
size={"small"} 
id="box" options={myOptions} 
getOptionLabel={(option: string) => option} 
renderInput={(params) => <TextField {...params} variant="outlined" /> } 
classes={{ input: classes.smallFont }} />

Instead of specifying a class for "input," consider defining one for "inputRoot" to apply a class at the input root element (depending on your desired outcome).

To update the className in the renderInput function, modify it from the params.

const customStyles = makeStyles((theme) => ({     
    customOptions: {
        fontSize: '12px',
        color: 'red'
    }
}));


    <Autocomplete key={index}
    size="small"
    value={combo.value}
    options={combo.options}
    renderOption={(option) => (
        <Typography className={classes.customOptions}>{option.name}</Typography>
    )}
    getOptionLabel={(option) => option.name}
    renderInput={(params) => {
        params.inputProps.className = classes.customOptions
        return <TextField
            {...params} label={combo.text}
            variant="outlined"
        />
    }
    }
    onChange={(event, newValue) => {
        combo.onChange(newValue)
    }}
/>

For me, I encountered a situation where I needed to enlarge the font size of a label, and I managed to achieve this using the following method

Resolution:

TextFieldProps={{
    error: props.error,
    helperText: props.helperText,
    InputLabelProps: {
        required: props.required,
        style: {
            fontSize: 18,
        },
    },
}}

Step-by-Step Solution:

<Autocomplete
    freeSolo
    fullWidth={true}
    label={props.label}
    margin={'noraml'}
    multiple={false}
    name={props.name}
    isOptionEqualToValue={useCallback((option, value) => option.label === value.label, [])}
    value={props.value}
    options={props.options}
    ref={selectRef}
    placeholder={props.placeholder}
    disabled={props.disabled}
    TextFieldProps={{
        error: props.error,
        helperText: props.helperText,
        InputLabelProps: {
            required: props.required,
            style: {
                fontSize: 18,
            },
        },
    }}
    renderInput={useCallback(params => (
        <TextField {...params} variant='standard'/>
    ), [])}
    onChange={useCallback((e, v) => {
        if (typeof v === 'object' && v !== null) {
            _onChange(e, v)
        } else {
            _onChange(e, {label: ''})
        }
    }, [])}
