How to style react-select options

问题

What's the best way to style a react-select component's (https://github.com/JedWatson/react-select) options?

I can target the select itself just fine, with something like:

...
import Select from 'react-select'
...
const styles = {
  fontSize: 14,
  color: 'blue',
}
<Select
    options={[1,2,3,4]}
    placeholder={'Select something'}
    clearable={false}
    style={styles.select}
/>

The problem is, the actual options when the select is expanded remain styled as the default. How can I target these options for styling?

Here is an example of what I'm talking about. I can style the placeholder, but not the options:

react select v2 (update)

This new version introduces a new styles-api and some other major changes.

Custom Styles

Style individual components with custom css using the styles prop.

const colourStyles = {
  control: styles => ({ ...styles, backgroundColor: 'white' }),
  option: (styles, { data, isDisabled, isFocused, isSelected }) => {
    const color = chroma(data.color);
    return {
      ...styles,
      backgroundColor: isDisabled ? 'red' : blue,
      color: '#FFF',
      cursor: isDisabled ? 'not-allowed' : 'default',
      ...
    };
  },
  ...
};

export default () => (
  <Select
    defaultValue={items[0]}
    label="Single select"
    options={items}
    styles={colourStyles}
  />
);

Now there is better documentation and more clear examples on the project's website:

Custom classNames

You can provide a custom className prop to the component, which will be added to the base .Select className for the outer container. The built-in Options renderer also support custom classNames.

Add your custom className as a property to objects in the options array:

const options = [
    {label: "one", value: 1, className: 'custom-class'},
    {label: "two", value: 2, className: 'awesome-class'}
    // more options...
];
...
<Select options={options} />

MenuRender

The menuRenderer property can be used to override the default drop-down list of options.

optionClassName String The className that gets used for options

Example: react-select/master/src/utils/defaultMenuRenderer.js

回答2:

@btzr's answer is correct, and styling react-select using CSS classes is (relatively) easy.

However, it is difficult to style menu items because every time you open the menu and try to inspect the items, the menu closes again.

What helps is to (temporarily) specify menuIsOpen={true} parameter, which will keep menu open for easier inspection.

I got use style:

const options = [
    {label: "one", value: 1, style: { color: 'red' }},
    {label: "two", value: 2, style: { color: 'blue' }}
    // more options...
];
...
<Select options={options} />

回答4:

const CustomStyle = {
  option: (base, state) => ({
    ...base,
    backgroundColor: state.isSelected ? {Color1} : {Color2},
  })
}
<Select styles={customStyle} >

There are more options for this. Have a look at the documentation for styling.
