How to remove Clear button on Autocomplete and show only text

There is a dedicated prop to disable the Icon. try the prop "disableClearable" on the Autocomplete component it is here in the documentation:

<Autocomplete
    {...defaultProps}
    id="disable-clearable"
    disableClearable
    renderInput={(params) => <TextField {...params} label="disableClearable" 
    margin="normal" />}
/>

Try this :

import React, { useState } from "react";
import Checkbox from "@material-ui/core/Checkbox";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";
import CheckBoxOutlineBlankIcon from "@material-ui/icons/CheckBoxOutlineBlank";
import { ListItemText } from "@material-ui/core";
import CheckBoxIcon from "@material-ui/icons/CheckBox";
import MenuItem from "@material-ui/core/MenuItem";
import { List } from "react-virtualized";
import faker from "faker";

const icon = <CheckBoxOutlineBlankIcon fontSize="small" />;
const checkedIcon = <CheckBoxIcon fontSize="small" />;

const ListboxComponent = React.forwardRef(function ListboxComponent(
  props,
  ref
) {
  const { children, role, ...other } = props;
  const itemCount = Array.isArray(children) ? children.length : 0;
  const itemSize = 36;

  return (
    <div ref={ref}>
      <div {...other}>
        <List
          height={250}
          width={300}
          rowHeight={itemSize}
          overscanCount={5}
          rowCount={itemCount}
          rowRenderer={(props) => {
            return React.cloneElement(children[props.index], {
              style: props.style
            });
          }}
          role={role}
        />
      </div>
    </div>
  );
});

const myDAta = Array.from(new Array(10000)).map(() => {
  return { name: faker.name.findName() };
});

myDAta.unshift({ name: "ALL" });

export default function CheckboxesTags() {
  const [selectedFilm, setSelectedFilm] = useState([]);
  const onCloseHandle = () => {
    console.log("Closed");
  };
  return (
    <Autocomplete
      id="checkboxes-tags-demo"
      ListboxComponent={ListboxComponent}
      options={myDAta}
      onChange={(e, film) => {
        console.log(e.target);
        setSelectedFilm(film);
      }}
      onClose={onCloseHandle}
      getOptionLabel={(option) => option.name}
      // fullWidth
      renderOption={(option) => <>{option.name}</>}
      closeIcon=""

      style={{ width: 300, maxHeight: "1px" }}
      renderInput={(params) => (
        <TextField
          {...params}
          variant="outlined"
          label="Checkboxes"
          placeholder="Favorites"
        />
      )}
    />
  );
}

Return all params, without endAdornment in TextField

renderInput={(params) => <TextField {...params} 
InputProps={{ ...params.InputProps, endAdornment : null }}
onPaste={handlePaste} variant='outlined'/>}

As of MUIv5 Autocomplete isn't in lab anymore and does things a bit different and gives you more customization on the display. Both the clear icon and the downarrow are in the InputProps.endAdornment that is passed into the renderInput function. So you can remove it before spreading to to TextField

 <Autocomplete
  options={options}
  renderInput={params => {
    const InputProps = { ...params.InputProps };
    InputProps.endAdornment = null;
    return (
      <TextField    
        {...params}
        InputProps={InputProps}
      />
    );
  }}
  openOnFocus  
  />
  

Note how InputProps is after the {...params} spread.

If you do this you'll need to add 'openOnFocus' prop since the downarrow won't be there to click to open the autocomplete.

MUI also adds some paddingRight to .MuiInput-root class to make some space for the clearIcon and downArrow, so if you're tight on space you might need to remove those, I ended up using an !important css rule on the TextField class, but we're still using the old JSS way. Not sure what the proper emotion styling way to do it would be.
