如何为react-select.js设置全局样式

Question

I would like to set global style for the react-select . For my understanding I can do 2 ways:

1. Using className and classNamePrefix and then target elements using CSS.

   PROS: I can use the same style everywhere

   CONS: Every new component must use exactly the same className and classNamePrefix

Example:

className='react-select-container'

classNamePrefix="react-select"

Result:

 <div class="react-select-container"> <div class="react-select__control"> <div class="react-select__value-container">...</div> <div class="react-select__indicators">...</div> </div> <div class="react-select__menu"> <div class="react-select__menu-list"> <div class="react-select__option">...</div> </div> </div> </div> 

2. Create external javascript file with "Provided Styles and State"

   PROS: more flexible then CSS

   CONS: Every new component must use style property using imported external file.

Example:

 const customStyles = { option: (provided, state) => ({ ...provided, borderBottom: '1px dotted pink', color: state.isSelected ? 'red' : 'blue', padding: 20, }), control: () => ({ // none of react-select's styles are passed to <Control /> width: 200, }), singleValue: (provided, state) => { const opacity = state.isDisabled ? 0.5 : 1; const transition = 'opacity 300ms'; return { ...provided, opacity, transition }; } } const App = () => ( <Select styles={customStyles} options={...} /> ); 

What is the best way to style multiple react-select components? Will be possible to set style globally and every new react-select component use that style automatically?

Answer 1

One way to do it is to create your own select component like CustomSelect that you import instead of react-select where you set for one the custom style or theme like:

import React, { Component } from 'react'
import Select from 'react-select'

class CustomSelect extends Component {
  render() {

    const styles = {
      ...
      // what ever you need
    }

    return <Select styles={styles} {...this.props} />
  }
}

export default CustomSelect

I can't really tell if it's the best way or not but I've tried both of it and in a big project with many select it's the easiest way to maintain / modify it. Plus it's really convenient if at some point you need to have custom components.
