reactjs - 如何删除 react 选择中的栏？

Question

我正在尝试改进 react 选择的用户界面。我在网上做了一些研究，但我仍然不知道如何删除选择中的栏。

我可以设置控件组件的样式来删除栏吗？怎么办？

import React from 'react';
import chroma from 'chroma-js';

import { colourOptions } from './docs/data';
import Select from 'react-select';

const dot = (color = '#ccc') => ({
  alignItems: 'center',
  display: 'flex',

  ':before': {
    backgroundColor: color,
    borderRadius: 10,
    content: ' ',
    display: 'block',
    marginRight: 8,
    height: 10,
    width: 10,
  },
});

const colourStyles = {
  control: styles => ({ ...styles, backgroundColor: 'white' }),
  option: (styles, { data, isDisabled, isFocused, isSelected }) => {
    const color = chroma(data.color);
    return {
      ...styles,
      backgroundColor: isDisabled
        ? null
        : isSelected ? data.color : isFocused ? color.alpha(0.1).css() : null,
      color: isDisabled
        ? '#ccc'
        : isSelected
          ? chroma.contrast(color, 'white') > 2 ? 'white' : 'black'
          : data.color,
      cursor: isDisabled ? 'not-allowed' : 'default',
    };
  },
  input: styles => ({ ...styles, ...dot() }),
  placeholder: styles => ({ ...styles, ...dot() }),
  singleValue: (styles, { data }) => ({ ...styles, ...dot(data.color) }),
};

export default () => (
  <Select
    defaultValue={colourOptions[2]}
    label="Single select"
    options={colourOptions}
    styles={colourStyles}
  />
);

react-select 允许我们通过执行操作来控制组件

components={{
  IndicatorSeparator: () => null
}}

例如:

<Select
  id="search-commodity"
  options={comodityOptions}
  components={{
    IndicatorSeparator: () => null
  }}
/>
